I often use "Highlight Usages in File" (CtrlShiftF7) to highlight/un-highlight symbols within the file and it works great.
However, when I try "Next Occurence" (CtrlAltDown) or "Previous Occurence" (CtrlAltUp), nothing happens. Those actions don't even appear in the "Go To" menu.
I use the default keyboard mapping (I'm on windows vista) and I though there was a conflict. I created a new mapping and remapped the action NEXT OCCURENCE to something very improbable to be already in use -> a two keystroke CtrlShiftAlt+M ... and still no reaction even though the action name appears on the status bar after the first keystroke.
Help needed here ;) !! I'm on 7.0.4
