When some menu (e.g. application menu or right-click-menu somewhere) or dropdown field is opened, keyboard shortcuts do not work. Not sure to where it belongs, so posting again in xfwm4, sorry.
That's perfectly normal, the menu grabs the keyboard and pointer, no other apps can access it.
Is there no way to work around this? Of course I can queue my shortcut actions, but it's not the way shortcuts should work I think.
