Non-standard keys are not bindable

ZyX created issue xonotic-data.pk3dir#1137 (closed) on 2012-03-21T03:56:53Z:

It is not possible to bind in xonotic the following keys:

Found on my mouse:

keycode 122 (keysym 0x1008ff11, XF86AudioLowerVolume)
keycode 123 (keysym 0x1008ff13, XF86AudioRaiseVolume)

On keyboard: ESC replaced by F13 (keycode 9 (keysym 0xffca, F13)). All these keys emit «“” isn’t a valid key» in xonotic-sdl when I try to bind them from the gui.
