As far as I can tell, there is no way to figure out what hotkeys do other than just trying things randomly and seeing what happens. I’d love to see hotkeys when hovering over tools, like “Move (m)” etc.
Another good idea is to do like among others Gmail, and have a hotkey map available when you type question mark. That can show all kinds of things besides just the tools.
Lastly, I’d like to have more hotkeys. As far as I can tell, not every tool has one. Why not? In certain circumstances, you need to switch between tools that you almost never use regularly. For those times, it’s a pain to not have hotkeys. For instance, the Look Around tool.
Thanks for an otherwise great product! Loving the web version.
