'Cmd-c' shortcut doesn't work (on Mac) while 'Cmd-backspace' and 'C-c' does

[VasylBaran]

Summary

I'm loving helix. While trying to customize the shortcuts a bit I've added the following to my config.toml:

Cmd-c = "yank"
Cmd-v = "paste_after"

In this configuration 'paste_after' works but 'yank' doesn't (nothing happens)

If I trigger 'yank' in a usual way (Space + y) it works, so it's more about the shortcut rather than about method.

Similar trouble with 'S-backspace' assigned to "delete_selection" - nothing happens when it's 'S-backspace' but 'Cmd-backspace' works.

Reproduction Steps

Add the following to config.toml:

Cmd-c = "yank"
Cmd-v = "paste_after"

When I press "Cmd-c" (Command+C) I expected the selection to get copied (yanked). Instead, nothing happens.

@the-mikedavis thank you for adding support for Cmd key in 271c32f

I wonder, have you tried to assign any action to 'Cmd-c' shortcut inside config.toml file? Does it work for you and does it trigger the action?

Thanks again! ;-)

A Cmd-c binding works for me locally but I'm using Linux and Kitty. Either macOS or the terminal emulator might be eating that keypress (I would suspect macOS). Also note that super bindings (Cwd/Win/Meta) require a terminal that supports the enhanced keyboard protocol - I'm not sure off the top of my head whether Alacritty does. You can check by starting Helix with hx -vv and looking for a line like "[DEBUG] The keyboard enhancement protocol is supported in this terminal (checked in 3.140555ms)". (It will say "is not" if Alacritty doesn't support the enhanced keyboard protocol.)

you're absolutely right! The same shortcut works in kitty, but not in Alacritty. Although I do see "helix_tui::backend::crossterm [DEBUG] The keyboard enhancement protocol is supported in this terminal" so theoretically it "should" work. Thank you for your insight @the-mikedavis!

Cmd-c however doesn't work, not even in kitty =(

Cmd-S-c works, Cmd-c doesn't
