UI for available shortcuts

Maybe I’m missing something, but it happens very often that I find there is a certain shortcut available (latest example is cmd+O in notes) that I had no idea existed. In the cmd+O example - this is something that I regularly needed over the past weeks, I even considered adding a feature request for it. I’m sure there are tons of shortcuts that I don’t know about and at this point I cant think of a way to find out what they are, other than just trying our random combinations.

I do like the way Raycast does this - there is a UI for each available option in a given context and on each item, the shortcut for it is displayed.
