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 https://github.com/hyprwm/Hyprland/issues/2682 for example), but given that wev produces the expected output I don't think this is related to Hyprland.

研究方向
Investigate how OBS handles hotkey input under Wayland. Look at the source code in libobs/obs hotkey.c and the Wayland platform plugin (obs wl). Check if the numpad key codes like KP End are being filtered or ignored. Compare with the X11 implementation. There is a comment that wev produces the correct output, so the issue likely lies in OBS's key event processing for Wayland. Look for any code that checks for numlock state or filters non numeric numpad keys.
