It's very time-consuming typing things like
<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>T</kbd> to produce Ctrl+Alt+T. You have to switch the keyboard mode what feels like dozens of times.
It would be nice if there was a button that popped up a modal question, much like the hyperlink button does, to ask what the text on the keycap was, which would then insert the full
<kbd>Text entered</kbd> sequence with the text-entry cursor positioned just after it.
