Cut Keybinding Does not Work

[blueray453]

The following keybinding works.

bind \cx fish_clipboard_copy

But the following does not work.

bind \cx fish_clipboard_copy kill-selection

What might be the issue?

From https://fishshell.com/docs/current/cmds/bind.html:

Note

Special input functions cannot be combined with ordinary shell script commands. The commands must be entirely a sequence of special input functions (from bind -f) or all shell script commands (i.e., valid fish script). To run special input functions from regular fish script, use commandline -f (see also commandline). If a script produces output, it should finish by calling commandline -f repaint to tell fish that a repaint is in order.

fish_clipboard_copy is a normal script function.

The following works:

function ctrl_x_cut
    set -l cmdline_selection
    set cmdline_selection (commandline --current-selection | string collect)
    # set cmdline (commandline --current-buffer | string collect)

    if test -n "$cmdline_selection"
        printf '%s' $cmdline_selection | xclip -selection clipboard
        commandline -f kill-selection
        commandline -f end-selection
    end
end
