Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

Here's how it works:
  1. Anybody can ask a question
  2. Anybody can answer
  3. The best answers are voted up and rise to the top

In the Finder, the Cmd + Up and Cmd + Down shortcuts do not work (they have no effect whatsoever).

It works properly when I create a new account.

I tried the following:

  • removing and
  • emptying cache
  • repairing permissions
  • desactivating Quicksilver
  • reinitializing shortcuts in Systems Preferences

If you found something that fixed the problem, post it as a new answer, not just an edit to the question. – Wuffers Apr 19 '11 at 2:03
Agreed with @MarkSzymanski. If you figured out the problem, post your answer below in the answer box, then mark it as the accepted answer once enough time has passed to do so. I removed the answer from your question; please repost it below as a proper answer. – nhinkle Apr 19 '11 at 3:08
I could not do it because it was the first time I posted on superuser, and you have to wait 24h before posting an answer to your own question. – charlax Apr 21 '11 at 18:15

To solve it:

  • Activate Spaces in System Preferences
  • Disable the "Switch between spaces" shortcut by setting it to "-"
  • Disable Spaces if you want.
