Virgil Dupras f6ded7712e VE: add 't'
This is the first commit I do entirely in VE. It's a habit I'm planning
on taking as it helps a lot to find usability issues.

Sending 0xff to the port resets the keyboard, and then we have
to send groups we want to "listen" to, with a 0 in the group
bit. Thus, to know if *any* key is pressed, we send 0xff to
reset the keypad, then 0x00 to select all groups, if the result
isn't 0xff, at least one key is pressed.
