I’m still on Windows 10 (and MacOS), so I can’t test.
- Have you tried testing this in the Sandbox vault? Or testing with default theme and no CSS snippets, and no plugins? (Although I don’t know if that would affect the hotkey.)
- What is your Obsidian installer? If it’s older, consider downloading and reinstalling.
- In Windows 10, I can use Win+M to minimize everything. I guess you meant Ctrl-M for Windows?
- I can’t seem to find any app that responds to Ctrl-M to minimize.
- If you did mean Cmd-M (Win-M on a Mac keyboard maybe?) do all the other apps minimize and Obsidian stays open?
