Background:
Many questions require the user to describe used keyboard shortcuts.
These can be formatted through <kbd></kbd>
.
Suggestion:
I would like to suggest to add an icon to the composing editor to format keyboard shortcuts visually.
I suggest positioning the keyboard shortcut icon right after the Emphasis icon, also called the Italics icon, which looks like this:
I think it would look a little bit ugly there, but I don't care about that. What I do care about is the user experience factor. The proposed keyboard shortcut icon would look a little bit mean there, which would give users a visual cue that it's OK to be mean on the website, which is not a good design from a community perspective.
Stack Overflow has both Graphic Design and User Experience Q&A websites, so I would expect that suggestions like this one would attract quite a bit of professional interest on the Stack Overflow network generally.
There's an app for that!

And an extension, too:

And here's the extension's Git page:

One of those two should work for you.
<kbd>
tags aren't really used all that often, I don't think SE will be willing to put much effort into this.
kbd
formatting more visible. From my experience, many users are not even aware of it.
<kbd>
is never used and is probably not even implemented. The edit box is the same for all sites though so only global features will be added to it.
