XMonad.Hooks.DebugKeyEvents

- Usage

Description

A debugging module to track key events, useful when you can't tell whether xmonad is processing some or all key events.

Synopsis

- debugKeyEvents :: Event -> X All

# Usage

Add this to your handleEventHook to print received key events to the log (the console if you use `startx`/`xinit`, otherwise usually `~/.xsession-errors`).

         , handleEventHook = debugKeyEvents

If you already have a handleEventHook then you should append it:

         , handleEventHook = ... <> debugKeyEvents

Logged key events look like:

    keycode 53 sym 120 (0x78, "x") mask 0x0 () clean 0x0 ()

The `mask` and `clean` indicate the modifiers pressed along with the key; `mask` is raw, and `clean` is what `xmonad` sees after sanitizing it (removing `numberLockMask`, etc.)

For more detailed instructions on editing the logHook see the tutorial.
