Recently found out something weird about _BlendSrf.
It’s supposed to press Shift to edit symmetrically. However, in 7.14.22010.17002, 2022-01-10
I find that it controls Ortho instead as you can see in my screenshot.
Hello - I can see that Alt & Shift also act on Osnaps and Ortho (only Ortho on Windows) However, it all works if you have the key down when you click on the control - once the point is active, you can let up on the modifier key and keep the same (symmetrical or rotating) action. Does that work?
