Use ? and Alt+? to open keyboard shortcuts panel

[iandunn]

Problem

I can never remember the keyboard shortcut that reveals the list of keyboard shortcuts.

control+alt+h feels cumbersome, unintuitive, and inconsistent with other popular web apps.

Proposed Solution

It seems like most web apps have standardized on ? as the key to open that panel, e.g., Trello and GitHub. That feels much more intuitive to me. Of course that won't work if the user is focused on an input field, but in those cases a single modifier like Alt+? or Control+? would solve that.

The current shortcut should probably remain for back-compat. Alt+? and Control+? don't seem to have any conflicts on OS X + Firefox, but I haven't tested beyond that.

Recommended reading: #3218 #8316. The tl;dr is that there are a lot of issues with Meta+? as a shortcut, and the likely long term solution is to allow users to remap keyboard shortcuts to something that makes sense based on their keyboard layout or other installed apps.

(Edit: to be clear I also wish it could be meta+? because muscle memory. Just pointing out that there was a lot of discussion before deliberately deciding not to use meta+?.)

Thanks for pointing that out.

It seems like we could still use ? when an text/textarea input isn't focused.

Maybe the rest of this ticket is a duplicate of #3218, though? Those conversations are pretty length, so I'll admit I didn't read all of them. Feel free to close this if you think it's already covered.

@tofumatt any thoughts on using ? when nothing is selected?

[tofumatt]

? works for me. Control + ? could work when inputs are selected, but we could also just go with ? to start with and iterate from there...

It's really / that would be the bound key.

When I initially tried implementing this, lots of people mentioned they don't have a / on their keyboards (many European keyboard layouts don't have it).

I discovered slack (and possibly gdocs) workaround this by binding both / and ., so we should probably do the same.

I haven't tested it, but IIRC Firefox uses / for Search, and many popular web apps do as well (e.g., Remember the Milk), so we might want to use it ourselves one day for something like #wp33566:comment:4.

Is this discussion still valid? If you can't remember the shortcut, you can check it from the options menu.
