Beginning Firefox Ubiquity

Been playing with Firefox Ubiquity add-in for the past month and found myself using these commands:

define (def) word

Gives definition of a word in Ubiquity popup.

map <location>

Shows Google Map in Ubiquity popup. If you press Enter, it opens Google Maps in a new tab.

tab <tab name>

Displays the named tab. For example, tab gmail would display the Gmail tab. Useful if when I open too many tabs and can't see tabs that are off-screen.

translate (tr)

Translate selected text to English in Ubiquity popup. I browse Malaysian news sites but my BM is rusty, so I like to check that I read some text correctly. The translation fails if there are proper names in the start of the text, so I still have to visit a translation site.

twitter (tw)

Update your Twitter status. You have to provide Firefox with your Twitter user name and login to send the update.
