[SUGGESTION] Clearly visible shortcut key tooltips/hints for commonly used functionalities

[liva]

Hello, I was referred to post this issue here as a reminder.

Would be nice if commonly used shortcut keys would have some kind of tooltips or indicators, to transition people over to using shortcut keys as soon as possible, with as little friction/effort (for the user) as possible.

It took me a while before I actually started using shortcut keys like Q to create a card.
A tooltip such as this:

Or perhaps a shortcut key hint under the export button would help too, eg:

(Might be a bit less intuitive though, unless that Q text has the tooltip popup instead of the button itself).

Other than that, I think an indicator for global Anki shortcut keys in the shortcut key cheat sheet would be helpful too.

This would make it more clear that those shortcut keys exist (personally, I forgot), and make it easier to check them.
