.SH COMMANDS
.PP
This section shows information about built-in commands.
Modal commands do not take any arguments, but instead change the
operation mode to read their input conveniently, and so they are meant
to be assigned to keybindings.
.SS quit (default \f[C]q\f[R])
.PP
Quit lf and return to the shell.
.SS up (default \f[C]k\f[R] and \f[C]<up>\f[R]), half-up (default \f[C]<c-u>\f[R]), page-up (default \f[C]<c-b>\f[R] and \f[C]<pgup>\f[R]), scroll-up (default \f[C]<c-y>\f[R]), down (default \f[C]j\f[R] and \f[C]<down>\f[R]), half-down (default \f[C]<c-d>\f[R]), page-down (default \f[C]<c-f>\f[R] and \f[C]<pgdn>\f[R]), scroll-down (default \f[C]<c-e>\f[R])
.PP
Move/scroll the current file selection upwards/downwards by one/half a
page/full page.
.SS updir (default \f[C]h\f[R] and \f[C]<left>\f[R])
.PP
Change the current working directory to the parent directory.
.SS open (default \f[C]l\f[R] and \f[C]<right>\f[R])
.PP
If the current file is a directory, then change the current directory to
it, otherwise, execute the \f[C]open\f[R] command.
A default \f[C]open\f[R] command is provided to call the default system
opener asynchronously with the current file as the argument.
A custom \f[C]open\f[R] command can be defined to override this default.
.SS jump-next (default \f[C]]\f[R]), jump-prev (default \f[C][\f[R])
.PP
Change the current working directory to the next/previous jumplist item.
.SS top (default \f[C]gg\f[R] and \f[C]<home>\f[R]), bottom (default \f[C]G\f[R] and \f[C]<end>\f[R])
.PP
Move the current file selection to the top/bottom of the directory.
A count can be specified to move to a specific line, for example, use
\f[C]3G\f[R] to move to the third line.
.SS high (default \f[C]H\f[R]), middle (default \f[C]M\f[R]), low (default \f[C]L\f[R])
.PP
Move the current file selection to the high/middle/low of the screen.
.SS toggle
.PP
Toggle the selection of the current file or files given as arguments.
.SS invert (default \f[C]v\f[R])
.PP
Reverse the selection of all files in the current directory (i.e.
\f[C]toggle\f[R] all files).
Selections in other directories are not affected by this command.
You can define a new command to select all files in the directory by
combining \f[C]invert\f[R] with \f[C]unselect\f[R] (i.e.
\f[C]cmd select-all :unselect; invert\f[R]), though this will also
remove selections in other directories.
.SS invert-below
.PP
Reverse the selection (i.e.
\f[C]toggle\f[R]) of all files at or after the current file in the
current directory.
.PP
To select a contiguous block of files, use this command on the first
file you want to select.
Then, move down to the first file you do \f[I]not\f[R] want to select
(the one after the end of the desired selection) and use this command
again.
This achieves an effect similar to the visual mode in Vim.
.PP
This command is experimental and may be removed once a better
replacement for the visual mode is implemented in \f[C]lf\f[R].
If you\[aq]d like to experiment with using this command, you should bind
it to a key (e.g.
\f[C]V\f[R]) for a better experience.
.SS unselect (default \f[C]u\f[R])
.PP
Remove the selection of all files in all directories.
.SS glob-select, glob-unselect
.PP
Select/unselect files that match the given glob.
.SS calcdirsize
.PP
Calculate the total size for each of the selected directories.
Option \f[C]info\f[R] should include \f[C]size\f[R] and option
\f[C]dircounts\f[R] should be disabled to show this size.
If the total size of a directory is not calculated, it will be shown as
\f[C]-\f[R].
.SS clearmaps
.PP
Remove all keybindings associated with the \f[C]map\f[R] command.
This command can be used in the config file to remove the default
keybindings.
For safety purposes, \f[C]:\f[R] is left mapped to the \f[C]read\f[R]
command, and \f[C]cmap\f[R] keybindings are retained so that it is still
possible to exit \f[C]lf\f[R] using \f[C]:quit\f[R].
.SS copy (default \f[C]y\f[R])
.PP
If there are no selections, save the path of the current file to the
copy buffer, otherwise, copy the paths of selected files.
.SS cut (default \f[C]d\f[R])

buffer, otherwise, copy the paths of selected files.
.SS paste (default \f[C]p\f[R])
.PP
Copy/Move files in the copy/cut buffer to the current working directory.
A custom \f[C]paste\f[R] command can be defined to override this
default.
.SS clear (default \f[C]c\f[R])

.SS cd
.PP
Change the working directory to the given argument.
.SS select
.PP
Change the current file selection to the given argument.
.SS delete (modal)

.PP
Read a shell command to execute and wait for a key press in the end.
.SS shell-async (modal) (default \f[C]&\f[R])
.PP
Read a shell command to execute asynchronously without standard I/O.
.SS find (modal) (default \f[C]f\f[R]), find-back (modal) (default \f[C]F\f[R]), find-next (default \f[C];\f[R]), find-prev (default \f[C],\f[R])
.PP

forward/backward direction and jump to the next/previous match.
.SS search (default \f[C]/\f[R]), search-back (default \f[C]?\f[R]), search-next (default \f[C]n\f[R]), search-prev (default \f[C]N\f[R])
.PP
Read a pattern to search for a file name match in the forward/backward
direction and jump to the next/previous match.
.SS filter (modal), setfilter
.PP
Command \f[C]filter\f[R] reads a pattern to filter out and only view
files matching the pattern.
Command \f[C]setfilter\f[R] does the same but uses an argument to set

.SS mark-remove (modal) (default \f[C]\[dq]\f[R])
.PP
Remove a bookmark assigned to the given key.
.SS tag
.PP
Tag a file with \f[C]*\f[R] or a single-width character given in the
argument.
You can define a new tag-clearing command by combining \f[C]tag\f[R]
with \f[C]tag-toggle\f[R] (i.e.
\f[C]cmd tag-clear :tag; tag-toggle\f[R]).
.SS tag-toggle (default \f[C]t\f[R])
.PP
Tag a file with \f[C]*\f[R] or a single width character given in the
argument if the file is untagged, otherwise remove the tag.
.SH COMMAND LINE COMMANDS
.PP
The prompt character specifies which of the several command-line modes
you are in.
For example, the \f[C]read\f[R] command takes you to the \f[C]:\f[R]
mode.
.PP
When the cursor is at the first character in \f[C]:\f[R] mode, pressing
one of the keys \f[C]!\f[R], \f[C]$\f[R], \f[C]%\f[R], or \f[C]&\f[R]
takes you to the corresponding mode.
You can go back with \f[C]cmd-delete-back\f[R] (\f[C]<backspace>\f[R] by
default).
.PP
The command line commands should be mostly compatible with readline
keybindings.
A character refers to a Unicode code point, a word consists of letters
and digits, and a unix word consists of any non-blank characters.
.SS cmd-escape (default \f[C]<esc>\f[R])
.PP
Quit command line mode and return to normal mode.
.SS cmd-complete (default \f[C]<tab>\f[R])
.PP

Autocomplete the current word with the menu selection.
You need to assign keys to these commands (e.g.
\f[C]cmap <tab> cmd-menu-complete; cmap <backtab> cmd-menu-complete-back\f[R]).
You can use the assigned keys to display the menu and then cycle through
completion options.
.SS cmd-menu-accept

.PP
Capitalize/uppercase/lowercase the current word and jump to the next
word.
.SH OPTIONS
.PP
This section shows information about options to customize the behavior.
Character \f[C]:\f[R] is used as the separator for list options
\f[C][]int\f[R] and \f[C][]string\f[R].
.SS anchorfind (bool) (default true)
.PP
When this option is enabled, the find command starts matching patterns
from the beginning of file names, otherwise, it can match at an
arbitrary position.
.SS autoquit (bool) (default false)
.PP
Automatically quit the server when there are no clients left connected.
.SS borderfmt (string) (default \f[C]\[rs]033[0m\f[R])
.PP
Format string of the box drawing characters enabled by the
\f[C]drawbox\f[R] option.
.SS cleaner (string) (default \[ga]\[ga]) (not called if empty)
.PP
Set the path of a cleaner file.
The file should be executable.
This file is called if previewing is enabled, the previewer is set, and
the previously selected file has its preview cache disabled.
The following arguments are passed to the file, (1) current file name,
(2) width, (3) height, (4) horizontal position, (5) vertical position of
preview pane and (6) next file name to be previewed respectively.
Preview cleaning is disabled when the value of this option is left
empty.
.SS copyfmt (string) (default \f[C]\[rs]033[7;33m\f[R])
.PP
Format string of the indicator for files to be copied.
.SS cursoractivefmt (string) (default \f[C]\[rs]033[7m\f[R]), cursorparentfmt string (default \f[C]\[rs]033[7m\f[R]), cursorpreviewfmt string (default \f[C]\[rs]033[4m\f[R])
.PP
Format strings for highlighting the cursor.
\f[C]cursoractivefmt\f[R] applies in the current directory pane,
\f[C]cursorparentfmt\f[R] applies in panes that show parents of the
current directory, and \f[C]cursorpreviewfmt\f[R] applies in panes that
preview directories.
.PP
The default is to make the active cursor and the parent directory cursor
inverted.
The preview cursor is underlined.
.PP
Some other possibilities to consider for the preview or parent cursors:
an empty string for no cursor, \f[C]\[rs]033[7;2m\f[R] for dimmed
inverted text (visibility varies by terminal), \f[C]\[rs]033[7;90m\f[R]
for inverted text with grey (aka \[dq]brightblack\[dq]) background.
.PP
If the format string contains the characters \f[C]%s\f[R], it is
interpreted as a format string for \f[C]fmt.Sprintf\f[R].
Such a string should end with the terminal reset sequence.
For example, \f[C]\[rs]033[4m%s\[rs]033[0m\f[R] has the same effect as
\f[C]\[rs]033[4m\f[R].
.SS cutfmt (string) (default \f[C]\[rs]033[7;31m\f[R])
.PP
Format string of the indicator for files to be cut.
.SS dircache (bool) (default true)
.PP
Cache directory contents.
.SS dircounts (bool) (default false)
.PP
When this option is enabled, directory sizes show the number of items
inside instead of the total size of the directory, which needs to be
calculated for each directory using \f[C]calcdirsize\f[R].
This information needs to be calculated by reading the directory and
counting the items inside.
Therefore, this option is disabled by default for performance reasons.
This option only has an effect when \f[C]info\f[R] has a \f[C]size\f[R]
field and the pane is wide enough to show the information.
999 items are counted per directory at most, and bigger directories are
shown as \f[C]999+\f[R].
.SS dirfirst (bool) (default true)
.PP
Show directories first above regular files.
.SS dironly (bool) (default false)
.PP
Show only directories.
.SS dirpreviews (bool) (default false)
.PP
If enabled, directories will also be passed to the previewer script.
This allows custom previews for directories.
.SS drawbox (bool) (default false)
.PP
Draw boxes around panes with box drawing characters.
.SS dupfilefmt (string) (default \f[C]%f.\[ti]%n\[ti]\f[R])
.PP
Format string of file name when creating duplicate files.
With the default format, copying a file \f[C]abc.txt\f[R] to the same
directory will result in a duplicate file called
\f[C]abc.txt.\[ti]1\[ti]\f[R].
Special expansions are provided, \f[C]%f\f[R] as the file name,
\f[C]%b\f[R] for the basename (file name without extension),
\f[C]%e\f[R] as the extension (including the dot) and \f[C]%n\f[R] as
the number of duplicates.
.SS errorfmt (string) (default \f[C]\[rs]033[7;31;47m\f[R])
.PP
Format string of error messages shown in the bottom message line.
.PP
If the format string contains the characters \f[C]%s\f[R], it is
interpreted as a format string for \f[C]fmt.Sprintf\f[R].
Such a string should end with the terminal reset sequence.
For example, \f[C]\[rs]033[4m%s\[rs]033[0m\f[R] has the same effect as
\f[C]\[rs]033[4m\f[R].
.SS filesep (string) (default \f[C]\[rs]n\f[R])
.PP
File separator used in environment variables \f[C]fs\f[R] and
\f[C]fx\f[R].
.SS findlen (int) (default 1)
.PP
Number of characters prompted for the find command.
When this value is set to 0, find command prompts until there is only a
single match left.
.SS globfilter (bool) (default false)
.PP
Patterns are treated as globs for the filter command, see
\f[C]globsearch\f[R] for more details.
.SS globsearch (bool) (default false)
.PP
When this option is enabled, search command patterns are considered as
globs, otherwise, they are literals.
With globbing, \f[C]*\f[R] matches any sequence, \f[C]?\f[R] matches any
character, and \f[C][...]\f[R] or \f[C][\[ha]...]\f[R] matches character
sets or ranges.
Otherwise, these characters are interpreted as they are.
.SS hidden (bool) (default false)
.PP
Show hidden files.
On Unix systems, hidden files are determined by the value of
\f[C]hiddenfiles\f[R].
On Windows, files with hidden attributes are also considered hidden
files.
.SS hiddenfiles ([]string) (default \f[C].*\f[R] for Unix and \[ga]\[ga] for Windows)
.PP
List of hidden file glob patterns.
Patterns can be given as relative or absolute paths.
Globbing supports the usual special characters, \f[C]*\f[R] to match any
sequence, \f[C]?\f[R] to match any character, and \f[C][...]\f[R] or
\f[C][\[ha]...]\f[R] to match character sets or ranges.
In addition, if a pattern starts with \f[C]!\f[R], then its matches are
excluded from hidden files.
To add multiple patterns, use \f[C]:\f[R] as a separator.
Example: \f[C].*:lost+found:*.bak\f[R]
.SS hidecursorinactive (bool) (default false)
.PP
Hide the cursor when the terminal or tmux pane loses focus.
.SS history (bool) (default true)
.PP
Save command history.
.SS icons (bool) (default false)
.PP
Show icons before each item in the list.
.SS ifs (string) (default \[ga]\[ga])
.PP
Sets \f[C]IFS\f[R] variable in shell commands.
It works by adding the assignment to the beginning of the command string
as \f[C]IFS=...; ...\f[R].
The reason is that \f[C]IFS\f[R] variable is not inherited by the shell
for security reasons.
This method assumes a POSIX shell syntax so it can fail for non-POSIX
shells.
This option has no effect when the value is left empty.
This option does not have any effect on Windows.
.SS ignorecase (bool) (default true)
.PP
Ignore case in sorting and search patterns.
.SS ignoredia (bool) (default true)
.PP
Ignore diacritics in sorting and search patterns.
.SS incsearch (bool) (default false)
.PP
Jump to the first match after each keystroke during searching.
.SS incfilter (bool) (default false)
.PP
Apply filter pattern after each keystroke during filtering.
.SS info ([]string) (default \[ga]\[ga])
.PP
A list of information that is shown for directory items at the right
side of the pane.
Currently supported information types are \f[C]size\f[R],
\f[C]time\f[R], \f[C]atime\f[R], and \f[C]ctime\f[R].
Information is only shown when the pane width is more than twice the
width of information.
.SS infotimefmtnew (string) (default \f[C]Jan _2 15:04\f[R])
.PP
Format string of the file time shown in the info column when it matches
this year.
.SS infotimefmtold (string) (default \f[C]Jan _2 2006\f[R])
.PP
Format string of the file time shown in the info column when it
doesn\[aq]t match this year.
.SS mouse (bool) (default false)
.PP
Send mouse events as input.
.SS number (bool) (default false)
.PP
Show the position number for directory items on the left side of the
pane.
When the \f[C]relativenumber\f[R] option is enabled, only the current
line shows the absolute position and relative positions are shown for
the rest.
.SS numberfmt (string) (default \f[C]\[rs]033[33m\f[R])
.PP
Format string of the position number for each line.
.SS period (int) (default 0)
.PP
Set the interval in seconds for periodic checks of directory updates.
This works by periodically calling the \f[C]load\f[R] command.
Note that directories are already updated automatically in many cases.
This option can be useful when there is an external process changing the
displayed directory and you are not doing anything in lf.
Periodic checks are disabled when the value of this option is set to
zero.
.SS preserve ([]string) (default \f[C]mode\f[R])
.PP
List of attributes that are preserved when copying files.
Currently supported attributes are \f[C]mode\f[R] (i.a.
access mode) and \f[C]timestamps\f[R] (i.e.
modification time and access time).
Note that preserving other attributes like ownership of change/birth
timestamp is desirable, but not portably supported in Go.
.SS preview (bool) (default true)
.PP
Show previews of files and directories at the rightmost pane.
If the file has more lines than the preview pane, the rest of the lines
are not read.
Files containing the null character (U+0000) in the read portion are
considered binary files and displayed as \f[C]binary\f[R].
.SS previewer (string) (default \[ga]\[ga]) (not filtered if empty)
.PP
Set the path of a previewer file to filter the content of regular files
for previewing.
The file should be executable.
The following arguments are passed to the file, (1) current file name,
(2) width, (3) height, (4) horizontal position, and (5) vertical
position of preview pane respectively.
SIGPIPE signal is sent when enough lines are read.
If the previewer returns a non-zero exit code, then the preview cache
for the given file is disabled.
This means that if the file is selected in the future, the previewer is
called once again.
Preview filtering is disabled and files are displayed as they are when
the value of this option is left empty.
.SS promptfmt (string) (default \f[C]\[rs]033[32;1m%u\[at]%h\[rs]033[0m:\[rs]033[34;1m%d\[rs]033[0m\[rs]033[1m%f\[rs]033[0m\f[R])
.PP
Format string of the prompt shown in the top line.
Special expansions are provided, \f[C]%u\f[R] as the user name,
\f[C]%h\f[R] as the hostname, \f[C]%w\f[R] as the working directory,
\f[C]%d\f[R] as the working directory with a trailing path separator,
\f[C]%f\f[R] as the file name, and \f[C]%F\f[R] as the current filter.
\f[C]%S\f[R] may be used once and will provide a spacer so that the
following parts are right aligned on the screen.
The home folder is shown as \f[C]\[ti]\f[R] in the working directory
expansion.
Directory names are automatically shortened to a single character
starting from the leftmost parent when the prompt does not fit the
screen.
.SS ratios ([]int) (default \f[C]1:2:3\f[R])
.PP
List of ratios of pane widths.
Number of items in the list determines the number of panes in the UI.
When the \f[C]preview\f[R] option is enabled, the rightmost number is
used for the width of the preview pane.
.SS relativenumber (bool) (default false)
.PP
Show the position number relative to the current line.
When \f[C]number\f[R] is enabled, the current line shows the absolute
position, otherwise nothing is shown.
.SS reverse (bool) (default false)
.PP
Reverse the direction of sort.
.SS roundbox (bool) (default false)
.PP
Draw rounded outer corners when the \f[C]drawbox\f[R] option is enabled.
.SS ruler ([]string) (default \f[C]acc:progress:selection:filter:ind\f[R])
.PP
This option is deprecated in favor of using the \f[C]rulerfmt\f[R]
option (see below).
List of information shown in status line ruler.
Currently supported information types are \f[C]acc\f[R],
\f[C]progress\f[R], \f[C]selection\f[R], \f[C]filter\f[R],
\f[C]ind\f[R], \f[C]df\f[R] and names starting with \f[C]lf_\f[R].
\f[C]acc\f[R] shows the pressed keys (e.g.
for bindings with multiple key presses or counts given to bindings).
\f[C]progress\f[R] shows the progress of file operations (e.g.
copying a large directory).
\f[C]selection\f[R] shows the number of files that are selected, or
designated for being cut/copied.
\f[C]filter\f[R] shows \f[C]F\f[R] if a filter is currently being
applied.
\f[C]ind\f[R] shows the current position of the cursor as well as the
number of files in the current directory.
\f[C]df\f[R] shows the amount of free disk space remaining.
