** Description changed:

  I frequently use the Super + [0-9] keyboard shortcuts to switch to
  specific applications. However, these shortcuts usually fail to work
  when executed quickly. In order to ensure a successful application
  switch, I have to hold down the super key for at least half a second
  (long enough for the launchers to appear on the left) before pressing a
  number key. If I press the number key too soon after starting to hold
  down the super key, Unity simply acts like I had not pressed the number
  key at all. It either shows the Dash if I let go of the super key fast
  enough or if I keep holding it down, it shows the shortcut overlay (i.e.
  whatever would have happened anyway if I never pressed the number key at
  all).
  
- This was a problem in 11.10 and is still a problem in 12.04. It really
- breaks my flow when it happens and I end up holding down super and
- mashing the number keys repeatedly until the right applications finally
- comes up.

  Note that it does not always open the dash, it's merely one of many side
  effects. More often than not it will just not register the change and
  write "2" or "3" into whatever program I'm using at the time (A severe
  annoyance when using vim, let me tell you!)
