Terminal Emulator - Interactive shell on vsplit?

[StatPal]

Hi, I'm new to micro. On the main page, it is written that,

Terminal Emulator
Run a real interactive shell from within micro. You could open up a split with code on one side and bash on the other -- all from within micro.

I need this functionality in an interactive line-by-line shell execution side-by-side/REPL fashion, often needed for an interpreted language. Unfortunately I couldn't find anything after some online search. Can anyone please show me some way?

[I can make a split and open a bash terminal there. But how to do the line-by-line evaluation? I think that some keybinding with copying + going to the other pane + pasting there + enter + coming back to the editor pane would work.]

Apart from that, is there any functionality where one can run a command (e.g., ls, maybe with the ctrl+e and run/term function) and paste that to the editor directly with some keybindings?

If you mean getting the standard output from a command into a buffer you can do that with the textfilter command. If the cursor has a selection that will get filtered through the command, but it works without a selection as well so you can do textfilter ls.

Thank you so much. The textfilter works perfectly for the second purpose.
