Description Beth Tibbitts

2011-10-31 11:05:11 EDT

Mark Occurrences formerly had a button in the toolbar (looks like a yellow highlighter) to toggle it on/off.
In fact the helps says it still does. 
http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.cdt.doc.user%2Freference%2Fcdt_u_toolbar.htm
But it's been missing for a while.

This can be annoying to figure out how to turn off if you don't know.
Because just double-clicking on a variable in the editor turns it on.
I used to turn it off with 
Alt-shift-O   but on my Mac this *also* adds an 'o' character in the file being edited.
But it does turn it off.

Upon further investigation (like reading the hover help on the button in the Plug-in Dev Perspective, where it still resides) maybe I'm supposed to do Alt-Cmd-O (aka Option-Cmd-O on Mac)
and this does toggle it without inserting a character.

I always like to show this in tutorials and I'm about to do another one.
How *should* the user be turning it off - does something work consistently in all platforms?
Can we put the button back into the C/C++ perspective?

This works for me.
Note that the button appears and enables only when a C/C++ Editor has the focus.
We haven't changed that behavior for a very long time and it is exactly the same as JDT's.

Since bug 298696 we have aligned key bindings with those of JDT, ie. on carbon you need to press Option+Command+O to toggle mark occurrences.

Are you maybe using some C/C++ Editor derivative?

Aha! you are exactly right. This is the Remote C/C++ Editor because RDT is installed.
I can't believe I never thought of that

Thanks; need to see how to get it fixed in the remote editor

Just add an actionSetPartAssociation extension for the RDT editor:

      <actionSetPartAssociation
            targetID="org.eclipse.cdt.ui.text.c.actionSet.presentation">
         <part id="insert-rdt-editor-id-here"/>
      </actionSetPartAssociation>
