<keycap> and </keycap> denote (keyboard) key names e.g. Enter
<keycap></keycap> can also be used around groups of keys to be used concurrently, e.g. Ctrl + Alt + F1 to launch a virtual terminal. (Note that "(space)+(space)" is used to link keys to be pressed concurrently).
Sequences of menu choices should use <menuchoice> and </menuchoice> for example View -> Message List -> Aggregation -> Standard Mailing List
In general, if the user needs to choose an element, even if it is not in a menu, the <menuchoice></menuchoiсe> markup should be used.
