MacOS - CapsLock, Shift, Control, fn, option, cmd not logged by debug view

[yorschor]

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

macOS

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

No response

WezTerm version

20240812-215703-30345b36

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

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

I tried configuring CapsLock as the leader key as i have done on windows but i cant get it to even show when I enable "config.debug_key_events"
I would assume that I would see the raw/physical input logged here?
Mind me this is MacOS Sequoia 24A5331b. I don´t know if that makes any difference.

I tried around with use_ime among others.
I also made sure that the keys work otherwise. Karabiner elements Event viewer logs everything normally

To Reproduce

1. Install Wezterm
2. set config.debug_key_events = true in the config file
3. Press one of the following keys "CapsLock, Shift, Ctrl, Option, CMD"

Configuration

local wezterm = require("wezterm")
local config = {}
local act = wezterm.action

if wezterm.config_builder then
config = wezterm.config_builder()
end
...
config.debug_key_events = true
...
config.animation_fps=60
return config

Expected Behavior

I would expect that all keys emit at least a physical/raw keyevent so that the can be used.

Update: It seems to be the same for me on the release version of MacOS Sequoia.

On a MBP M4 with Sequoia 15.1 I have the same issue.
I have been trying to make this work

config.keys = {
  -- Clears the scrollback and viewport leaving the prompt line the new first line.
  {
    key = 'K',
    mods = 'CMD',
    action = act.ClearScrollback 'ScrollbackAndViewport',
  }
}

but nothing happens, although the action works on the defaul terminal and CMD + V does correctly paste in Wezterm.

Enabled key logging, and noticed that CMD is not recognized at all. Doing CMD + V leads to a log where only the V is recognized

07:56:12.600  INFO   wezterm_gui::termwindow::keyevent > key_event RawKeyEvent { key: Char('v'), modifiers: NONE, leds: (empty), phys_code: Some(V), raw_code: 9, repeat_count: 1, key_is_down: false, handled: Handled(false) }

@clombion I'm confused about this too. You should use lowercase k because K is actually SHIFT+K (key = k, mods = "SHIFT" is same as key = K).

This working as expected:

{ key = 'k', mods = 'CMD', action = wezterm.action.ClearScrollback 'ScrollbackAndViewport' }
