Searching more efficiently in the dictionary!
This is for the Leopard version of dictionary. The dictionary on Leopard includes searching on Wikipedia by default. This changed the way I use the dictionary because if you keep "All" selected so that it searches both the Dictionary and the Thesaurus, it will also search Wikipedia and slow everything down. The way I do it now is that I switch between Dictionary and Thesaurus to keep everything going fast. The disadvantage is that I have to use the mouse to switch. There is a very cool Safari-like keyboard shortcut however. Just like how you can access bookmarks in Safari, using "Command-0", "Command-1", "Command-2" and so forth, will switch dictionary instantly. It is obvious which shortcut goes with which, because it follows the order like in the top bar.
