Inn previous versions, there has been a Keyboard Shortcuts PDF file. Is there one for SU 2022 Pro? If so, where?
You can download the Quick Reference from Getting Started in SketchUp | SketchUp Help Scroll down to section 4. The keyboard shortcuts haven’t really changed, though. If you have the Sketchucation ExtensionStore tool installed you can generate a list of keyboard shortcuts including your custom ones.
