I edited a question on SO. My edit was approved, but only after it was modified to change an instance of code formatting
to keystroke formatting. I did not know how to format as a keystroke, so it appears there is a hidden combination of SO HTML that does it. At that point, I looked it up through edit, but have already forgotten what it is.
Could this be added as a button to the WYSIWYG editor?

anywhere in your original post, I thought you were asking about how it works. (So did blahdiblah in their answer.) Very well then: duplicate of Please add a toolbar button or keyboard shortcut for the Keyboard style, but that has been closed...
