Not trying to come off as confrontational, just my 2¢.
I've never understood the almost subtle elitism behind being able to use Vim without a mouse because "moving your hand to the mouse is slow". If a problem is so simple my writing/editing a solution for it is constrained by... the time it takes my hand to move to my mouse... I usually just fire up nano.
If I used the IDEs you use, and you suggested to me a way of using them more efficiently, I wouldn't accuse you of elitism. I'd thank you for showing me something new and improving the way I work.
Have you ever witnessed somebody using a mouse to move between form fields? My bet is you at least thought about telling them they can use the tab key. You probably wouldn't expect them to come back with some comment about the subtle elitism behind using the tab key.
If you eat soup with a fork, you don't know how to use silverware. If you drive nails with a ball-peen hammer, you don't know how to use hammers. That's not hammer or silverware elitism.
IMO, using a mouse in vim shows that you don't know vim. You can still get the job done, but why not commit to using the tool as intended?
