If you use the firefox add-on http://labs.mozilla.com/projects/ubiquity/, here's a way to make commands for easy searching of the wiki and forums.
If you already have Ubiquity installed, go to a wiki or forum page and click inside the search box. Hit Alt+Space (or whatever keys you set to open it) and type in create search command [what you want the command to be called] and execute.
the link to ubiquity is dead. here's the correct one: https://wiki.mozilla.org/Labs/Ubiquity - however, the link says the project is on indefinite hiatus… not sure whether we should keep this wiki-article here. rhowaldt
