Still finding a couple of teething problems upgrading to ZB 2021. One of them is a keyboard shortcut INSERT (on Windows 7) which seem to be applied to a camera movement. This may be my own doing; this may be new to 2021. I’ll find out in due course.
However, this brings me to my real point, in that the Keyboard shortcuts page and accompanying documentation hasn’t been updated for a while.

All hail the keyboard shortcuts. May they be updated!
