Zoom shortcut? How to use with no mouse (Wacom tablet or other tablet)

[ewebgh33]

Hi
How do we zoom in and out without a mouse?

I use a wacom tablet on both Windows11 and Mac.
Is there a keyboard shortcut to zoom? Like hold cntrl and drag, or shift and drag? Something?

I came to the github because I can't figure out how to use this thing. Where's the documentation? Searched the main github page for "doc", "docs" and "documentation" and nothing. So where is it, and where is the list of shortcuts?
For that matter where's the list of all the little icons you use and what they mean, etc

Badly documented extension.
