This issue makes some of the built-in keyboard shortcuts confusing and some unusable. It looks as though offering custom keyboard shortcuts is under consideration, and that may fix it. I’m posting this in case it wouldn’t. The issue may affect anyone using a keyboard layout that uses AltGr, though the underlying OS platform might make a difference. It would be nice if all the SN shortcuts as listed on the cheat sheet could reflect the actual keys used to produce the desired effects as the keys are named in the currently-configured keyboard layout. (Not necessarily as the physical keycaps may show.)
I’m using an international keyboard layout on Linux, specifically Spanish Dvorak. It uses an AltGr key to access a number of characters, including #. Also other keys like / are in different places, sometimes requiring a modifier like shift. With this situation, the shortcuts cheat sheet is sometimes correct, sometimes not. This affects usability.
For example, when I try to type a # to add a tag, I begin the key combination with AltGr. But pressing that alone pins or unpins the card, with the result that # is inaccessible for tagging. Instead, it starts the title of a new card. In the context of editing a card, pressing #, as for headings, works as expected.
A different example: when I toggle the shortcuts cheat sheet, I do press Ctrl+Shift first, but the shift works in combination with 7 to produce “/”. So in one sense the cheat sheet is correct (Ctrl+Shift+/), but with this keyboard, it’s really Ctrl+Shift+7.
There are other examples, but this may suffice to illustrate the issue.
