Wrt the `<kbd></kbd>` insertion, how about this simple scenario: user has `Shift+Alt+P` and wants to convert it to <kbd>Shift</kbd>+<kbd>Alt</kbd>+<kbd>P</kbd>

**Current scenario:** user highlights all three keys individually and highlights them one by one. Boring! :(

**Proposed scenario:** user highlights the entire string (`Shift+Alt+P`) at once, presses Alt-K, and voila! It converts to <kbd>Shift</kbd>+<kbd>Alt</kbd>+<kbd>P</kbd> :D

**Implementation problems:** I don't think there should be any. We only need to split the text selection by `-` or `+` characters, apply formatting individually to each one of them, and give the result back.
