I highlight usages in file for multiple symbols when I am looking for related items to extract into a new class.
Sometimes when I am doing this, I find that I highlighted something erroneously and wish to un-highlight it.
Currently multiple highlights work like a stack -- pressing escape removes the most recently added highlight.
If I the symbol I wish to un-highlight is far down the stack this is a pain.
I would like a toggle model where if I requested highlighting for a symbol already highlighted it would un-highlight.
Escape could continue to work as it currently does.
