I regularly copy something, double-click something else (generally a variable), and paste over it with ctrl-v. After installing productivity power tools, occasionally (I haven't been able to pinpoint the exact circumstances) it will open up the header file of the variable I pasted over, and refactor it to what I pasted. How do I prevent this?
When clicking on the variable with Ctrl held, the power tools will navigate to the declaration of the variable. (Which is a feature that I appreciate)
You have two choices:
