disable_default_key_bindings does not affect some of the behaviors of Ctrl+C (keybinding appears to be hardcoded)

[crabdancing]

What Operating System(s) are you seeing this problem on?

Linux Wayland

Which Wayland compositor or X11 Window manager(s) are you using?

kwin 5.27.9

WezTerm version

wezterm 20230712-072601-f4abf8fd

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

No, and I'll explain why below

Describe the bug

(Nightly is prohibitively difficult, as Wezterm does not currently have a supported Nix flake. That said, I'm reasonably confident this behavior is likely to have not changed recently.)

Ctrl+C moves the view down to the bottom of the window. Ordinarily, this is desirable behavior, as most

To Reproduce

1. Setup config disabling default key bindings
2. fill the terminal with test text (e.g., for i in 0..1000 { echo $i } if you are using Nushell)
3. scroll up and hit Ctrl+C

Configuration

local config = {}
config.disable_default_key_bindings = true;
return config

Expected Behavior

Expected Wezterm to not react to Ctrl+C, when default keybindings are disabled. Ctrl+C response should be an explicit keybinding, and not hardcoded or 'invisible'.

Logs

No response

Anything else?

No response

This behavior is not specific to Ctrl-c, all keys will scroll to the end.
Try to set scroll_to_bottom_on_input = false, although it won't scroll it will still send those keys but you won't see them

(note: with nu you can also do seq 1 100 to quickly write some output 🙃)

Woah! But Ctrl+Shift+C doesn't do it. I guess it's special behavior of the shift key, then? I should look at the code for input processing.

Also, I didn't know nushell had seq like Bash & Fish do. Thanks for the tip :D

Edit: looks like it works. Now all I'd like to do is get the scrolling behavior back, but for Ctrl+Q specifically. Maybe I can rig it up with some Lua?

[bew]

Yeah, I think using wezterm.action.ScrollToBottom should do it?
Ref: https://wezfurlong.org/wezterm/config/lua/keyassignment/ScrollToBottom.html

[crabdancing]

Oh, awesome! Is there a way of binding some code to a keybinding without intercepting the keybinding? When I do { key = 'q', mods = 'CTRL', action = act.ScrollToBottom }, it eats Ctrl+Q and the terminal stack can't respond to the keypress.

[bew]

Well the simplest solution here would be to use a act.Multiple action, to call act.ScrollToBottom then act.SendKey with the key you want to send.

Check these additional docs:

• https://wezfurlong.org/wezterm/config/lua/keyassignment/Multiple.html
• https://wezfurlong.org/wezterm/config/lua/keyassignment/SendKey.html

{ key = 'q', mods = 'CTRL', action = act.Multiple { act.ScrollToBottom, act.SendKey { key = 'q', mods = 'CTRL' } } } worked, thanks! :)
