… *how* long has the Shift + scroll-wheel combination meant "scroll left/right instead of the usual up/down", in multiple applications, without me knowing it?
I stumbled over it this evening, by accidentally nudging my scroll wheel in #Inkscape while holding down Shift for another reason. Wasn't sure if it was just Inkscape, so I tried it in #Firefox too while zoomed in on a large image, and it worked there as well.
That's probably a thing that everyone else has known for years and I'm one of today's lucky 10,000. But someone, or something, or some manual, could have _said!_
@simontatham It's been inconsistently available since the dawn of scroll wheels, and it's also super easy to miss! I think it was a setting even on the original Microsoft Intellimouse.
But don't feel bad, it's like how I was a UNIX user for like 25 years before finding out about the "cd -" shortcut to swap back to the previous working directory.
