Expected Behavior

The numpad End key is assigned to the chosen action.

Current Behavior

Nothing happens. The input field remains blank.

Steps to Reproduce

1. Run a Wayland compositor (I'm using Hyprland)
2. Turn off num-lock
3. Run wev
4. Press the "1" key on the numpad
5. Notice that it records that the button KP_End was pressed (distinct from the End key)
6. Close wev
7. Open OBS
8. Open Settings -> Hotkeys and select the input field for an unassigned action
9. Press the "1" key on the numpad

Anything else we should know?

Numeric inputs from the numpad work just fine (like "1" with num lock turned on). The equivalent non-numpad keys work fine (like the regular "End" key).

It could be that Hyprland is doing something weird in how it handles num lock (see hyprwm/Hyprland#2682 for example), but given that wev produces the expected output I don't think this is related to Hyprland.

We dont map special keypad face buttons (see:

obs-studio/libobs/obs-nix-wayland.c

Line 1027 in 578dc46

case XKB_KEY_KP_Equal:

)

Someone would need to add these or convince xkb to do the mapping back to the non-keypad versions.

Thanks for the pointer! So that means it would need to be added to:

Anywhere else?

a964194 is the last addition of new keys.

Whether they should be their own keys or map into normal end/pgdn/etc im not sure. Id probably just map them to the normal keys and not add extra keys. You should probably see what occurs in windows/mac for the same keys.
