Don't let applications grab full keyboard input
There are some applications (QEMU, dosbox) which grab all input when their windows are focused which means i3 does not handle its key bindings any more. While those two have their own key bindings to release the keyboard and the mouse cursor (CTRL+ALT for QEMU and CTRL+F10 for dosbox), I came across another application for which I could not find such bindings. It's the OgreSampleBrowser. Is there a way to prevent a random application to grab all my input? Or is there at least a way that i3 still reacts to its key bindings?
Ideas are appreciated!
