[wmx] Key bindings debugging with xev

Those two work for me. Can you check that key events shown with X's
xev utility match entries wmx's Config.h file?

For example, my Config.h file includes the lines:
#define CONFIG_USE_KEYBOARD   	       (DynamicConfig::config.useKeyboard())
#define CONFIG_ALT_KEY		       XK_Super_L
#define CONFIG_WANT_KEYBOARD_MENU      True
#define CONFIG_CLIENT_MENU_KEY	       XK_Menu

When I use xev, pressing my keyboard's left Windows key and the menu
key prints out entries containing and "keycode 115 (keysym 0xffeb,
Super_L)" and "keycode 117 (keysym 0xff67, Menu)" respectively.
Pressing that key combination shows wmx's menu.
