So I figured it is entirely possible for new users to impatiently click through the initial introductions and completely miss the ? pop-up keyboard shortcut.
In general, keyboard shortcuts are for power-users, as they are inherently not easy to discover unless fitting standardized behavior, which still has to be learned previously. Having a GUI element makes it easier to discover this quick help option.
A few possible, (to me) non-intrusive locations could be:
- As an icon to the left of the hamburger menu icon on the top bar
- As a
๐ Quick Helpitem in the opened menu - To the left of the
#icon in opened cells

Cheers,
Job
