The remote input plugin uses the Android user-specified keyboard to specify keystrokes to transmit to the linked desktop. It is not typically possible, when using this, to send modifier keys such as Alt- or Ctrl-, arrow keys, PageUp/PageDn, Esc, or function keys F1-F12. Some interface by which these keys could be sent would be very useful. Merely being able to send a few canned codes such as Alt-Tab or Alt-F4 would itself be useful.
