too fickle: half the time I endup also scrolling. ctrl-click is far more predictable. Same result, less "trying to press a thing designed to roll".

On most mouses that's not an issue (assuming no motoric problems). Ctrl-click, on the other hand, requires the use of both hands in most cases.

I've never had a mouse where it wasn't a problem. I don't buy uber-quality mouses, so I'm down in the trenches with the vast majority of mouse users with moderate-to-low quality hardware.

I'm also often using a laptop, on linux, and I do the middle-click-simulation (both buttons at once) with two hands, which is really annoying. I suppose I could fix it.

Also I always have my left hand on the keyboard, so for me it's not a problem to ctrl-click.

Ctrl+click doesn't work on a tab, though--have to hit the X.

My laptop has a middle click button ;)

That's a cool trick. Thank you.
