Hi all,
I have come up with a doubt regarding 2.1.4 character key shortcuts .
Could you please give me a good example of 2.1.4 SC.
In youtube, the letter "K" is the shortcut for play / Pause. In NVDA ,
"K" will take you to the next link. So, if you press "K" in youtube ,
it will take you to the next link rather than activating the Play /
Pause button. Is it a violation?
In Deque university, when we doing the course, "Alt + Ctrl + N " is
the command to go to the next page. But, if you are using NVDA, with
the provided key command, it will restart NVDA. It won't take you to
the next page.
What about it?
Please help me.

This still would pass. The screen reader user has the ability of by-passing the keystroke. As the letter 'k' supports non-screen readers as well.

The failure is related to the use of the letter 'k' based upon the SC. Not related to the screen reader. The SC references, not to use single letter shortcut keys as it impacts speech (voice recognition) users. The SC references:
https://www.w3.org/WAI/WCAG21/Understanding/character-key-shortcuts.html
Turn off
A mechanism is available to turn the shortcut off;
Remap
A mechanism is available to remap the shortcut to include one or more non-printable keyboard keys (e.g., Ctrl, Alt);
Active only on focus
The keyboard shortcut for a user interface component is only active when that component has focus.
Thus technically the app you mention in your example fails. If they used a modifier of ctrl, alt or both, then this would pass. The challenge here of course is to select something that does not impact the user agent.

The youtube example would fail because it uses simple (unmodified) keys as
shortcuts and the keys work no matter where you are on the page. If I tab
to the comment area or the "up next" section in youtube and press K, the
video plays or pauses. If the K key only worked when the video itself had
focus, then it would pass because that's "Active only on focus". Since
youtube doesn't have a way to turn off the keyboard shortcuts nor a way to
remap the letters, it fails.
Gmail (web interface), on the other hand, has a settings for turning on/off
shortcut keys so it passes.

So, if the Short cut for Pause / Play is Alt + Ctrl + K, will it pass?
even though there is no option to turn it off and remap it?

Yes as Alt+Ctrl+K is not "using only letter (including upper- and
lower-case letters), punctuation, number, or symbol characters". It
doesn't generate an actual character at all. So there's no chance this
would accidentally be triggered by a voice user.
