Kbd shortcuts

[buggyboy]

It would be nice to have keyboard shortcuts for Home, and Back. Maybe also a global shortcut that redirects all kbd input to Wireboard even if its window is minimized (not active (and another "back to normal"))

Side note : what's the control on the top left corner for? Maybe it's obvious, but I can't see what's happening when changing it from message like icon to router like icon.

Thanks for the great app.
