UX is weirdly poor
For a UX design progress the UX on Figma is a bit nasty. Lots of poor decisions that make transitioning into the app from others really frustrating. Why reinvent the wheel when the round one worked so well? Press Z, expect zoom to toggle on, but no. It has to be held on. Press once to toggle on and again to toggle off should be standard for most functions like Zooming in. Alt key to Zoom out. Cmd G to group and again to ungroup. Simple.
