Manual zoom in/out within editor?

I'm fairly new to KWGT, so please forgive me - this is something pretty simple and basic, but I sure can't figure it out: How do you zoom in/out during editing? I discovered the switchable 'automatic zoom', which is great, but when you're trying to precisely align several items with one another, you really need to manually zoom in to that area. The usual pinch-to-zoom doesn't work - am I missing something? Thanks!

The only zoom that you have is the zoom that you talk, in the column in the right of the editor, you don't have pinch to zoom in Kwgt nor Klwp
