If you've read the December Macworld, perhaps you caught the "Secrets" article,
OS X's Most Underused Shortcut. It's all about the
Services menu, thus the topic title. (more on that in a minute) The article calls the Services menu a "little known and even more rarely used feature".
You find it in the application's menu; Safari or Firefox, etc. I don't know if it appears in other browsers, and the article reveals that Office won't let you use the Services selections.
It's pretty cool. Select some text, then go to Safari/Firefox/ Services and pick from the options there. You can look up the word in Dictionary, open Stickies and create one with the selected text automagically, search Google for the selected word(s), etc.
I couldn't get the Chinese Text Converter to do anything, but I assume that's because I don't have the necessary font installed. Another puzzle is the Speech option.
Start Speaking Text didn't work for me either. I tried to find some setting that needed to be switched on, but never got it to work. I'll have to play with it some more this weekend or sometime.
Check it out! And check out the Services Menu II topic....
I meant to put both topics in the Technical forum!
