keys a,l,k,left,right not working in other apps when TeleFrame is running

[thoschneider]

All keys that are mentioned in config.example.json, (a,l,k,left,right) don't work in other applications while TeleFrame is running. This is annoying because you can't even use ls in terminal or navigate left/right in an editor. Of course it is possible to start a terminal without X running (Ctrl+Alt+F1) then it works fine, but it would be nice if the mentioned keys would not be occupied "globally" by TeleFrame while X is running.
