Support Basics & Interface

just a simple question: how do i scale/grab on two specific axis. to grab on one axis, you simply tap x,y, or z but what about 2?

EDIT: im dead sure its possible because ive seen it in a video tutorial but now i cant find it:(

Shift + the axis you don’t want to use. So to move in the XY plane, it’s G->Shift-Z. Same goes for scaling.
