Ways to bound C-g to set_mark(False) only about xkeysnail HOT 3 CLOSED

In your config, before where you define the keymap containing c-g, put something like this:

def clear_mark_or(combo):
    if isinstance(combo, Key):
        combo = Combo(None, combo)

    def _clear_mark_or():
        if transform._mark_set:
            transform._mark_set = False
        else:
            return combo

    return _clear_mark_or

Now in the keymap define c-g like this:

    K("C-g"): clear_mark_or(K("esc")),

It seems to work as your first request (although like M-w, the selection is still visible until you subsequently move).

(edit: btw, I pretty much just copy-pasta'd that from the functions in transform.py)

Brilliant!!

I changed your code to return K("right") when the mark is reset. This becomes almost identical to Emacs behaviour, except for the fact that the cursor is always to the right of the selection even when the point should be to the left. I would have to somehow return K("left") when the "mark" is to the right of the "point" and K("right") otherwise, but I am not sure how to accomplish this.

This is also related to another thing that I wish I could change. In Emacs when C-SPC is pressed on an active selection, the previous selection is undone and the "mark" is at the "point". This would be easy to accomplish if I could figure out where the "point" is by sending the appropriate "left" or "right" keys.

What is this "selection" or "point" that you're referring to? All we know is what keys you hit - we know nothing about what you're editing, what is selected, where your cursor is or isn't at... so it's impossible to make decision based on such info.
