Jump to implementation invoked without click for virtual functions.

I'm using Qt Creator 3.1.2 on Mac OS X, where I can [command+click] to jump to the implementation of a function or declaration of a variable. It seems that this is invoked for virtual functions even without the mouse click. I.e. whenever I hold down "command" and move ever the call of a virtual function, it seems to jump to its definition. This is extremely irritating e.g. when doing some copy&pasting where "command" is held down for a while.

Could it be something in my settings that I have screwed up, or is it more likely a bug?
