title: Show pressed keys in VIM normal mode statusline
body: <p>I use VIM, the Colemak keyboard layout, and a Microsoft Natural 4000 keyboard. Since the Natural 4000 has differently-shaped keys, I could not change the keycaps. This means each key is labeled with an "incorrect" key -- I press the key that says "O" and it types "Y". </p>
  
  <p>That's fine in normal use, because I touch-type smoothly with Colemak and don't make many typos. But with VIM it presents a bit of a problem, because I often need to hit a key "out of sequence" -- i.e, just suddenly hit "g" without any context. For some reason that's harder to do, and I keep hitting the wrong keys.</p>
  
  <p>I'd like to be able to hit a prefix key (say, the leader key twice -- \) and then have any further keys I hit within 1-2 seconds shown on the status line.</p>
  
  <p>This way, I could quickly hit \ and then tap a key or two, and see what key it "really" is.</p>
  
  <p>Any ideas how I could make that happen?</p>
