I have an odd problem. In eclipse Ganymede, I used to be able to highlight a variable, and it would highlight the use of that variables in that method. However through some action I have now disabled it. Is there a way I can enable it? I tried searching Google, but since I don't know what the feature is called, its kinda tough.
Its a really useful feature, and its annoying that its not working.
I think the feature you mean is configured from:
Window -> Preferences -> Java -> Editor -> Mark Occurrences
There's a little "hiliter" icon on the toolbar - it toggles "Mark Occurrences".
You probably accidentally pressed it when trying to select a menu item at some point. I had a friend who did that with the "show selected element only" toolbar button...
You can either press it again or configure as Rytmis says.
Haha! I was trying to find a method using ctrl-shift-o and for some reason, I accidentally toggled alt-shift-o. That explains why I lost "mark occurencies".
Thanks, Adrian
