My question is similar to this one: http://stackoverflow.com/questions/385661/emacs-highlight-all-occurences-of-a-word
In Notepad++ editor, there's a convenient feature: if you select a word in your text (not necessarily a keyword), the word is highlighted throughout the text. Is there any similar way in a lightweight editor for Mac? I've tried Textwrangler and jedit, but they don't seem to have this very useful feature.
Thanks
