Comment 2 for bug 1400285

What's about adding another (invisible) component which is focused after pressing the universal CTRL (or ALT) key and unfocused after the next key press, so that the input is not routed to the terminal but can be combined with the CTRL (or ALT) key to one commit string just like it's done when pressing one of the predefined keys?

If for some reason that's not doable, it might be possible to capture the next keystroke which is sent to the terminal, send a backspace event to the terminal and then send the combined commit string.

What do you think?
