Highlight usages in file
I sometimes use ctrl-shift-f7 to highlight all usages of a variable in a file. My quesiton is once they are highlighted and I have what I need how do I make the variable not highlighted anymore? There isn't a readily apparent why how to turn it off.

Esc (it's only possible to clear all hightlights at once)
If you press escape, it will cancel the highlights.
Thanks! That has been annoying me. Now the question is why didn't I think about hitting the ESC key? It sounds obvious now since I know :)
Hmm, odd. ESC isn't working for me. The highligths remain even after hitting ESC.
Ahh ok. I use the VIM Emulator plugin and that intercepts the ESC key.
Is there anyway to turn them off other than the ESC key? I don't really want to have to turn of my VIM emulator everytime I want to turn off the highlighting.
You can remap the key if you want, I can't really think of any other way to turn them off!
Go to the Keymap settings, go into the "Editor Actions" branch and change the key for "Escape" to another key.
With regards to that functionality, I seem to remember that in the past when pressing ctrl-shift-f7 on different references, the color used was progressively different: do I remember well or not? If yes, was this provided by a plugin or is it a lost feature?
I am not sure what you mean by progressively different.
Idea has a feature that is a little strange to use, but quite useful:
If you do not have an editor selection Idea searches semantically,
for example with the caret after a variable called 'i', it will
highlight all occurences of that variable in purple (read and write
accesses in slightly different hues).
If you do have a selection, for example starting in front of 'i' and
ending after the 'i', Idea will just highlight each and every 'i'
character in the file in green.
BTW: Please note that if you highlight something the status bar says
"press Escape to remove the highlighting".
I also remember it and would love to get it back.
