The <para> and </para> show the start and end, respectively, of a paragraph. These delimiting marks are called "tags", and the content they contain (along with the tags) is called an "element". The <keycombo> tag has an extra piece of information specified: action="simul". This is called an "attribute," and makes the tag more specific. The words surrounded by & and ; are "entities". They are simply variables that expand to some other text, and are widely used in KDE documentation. See KDE Specialities for more information about entities. Tags, entities, comments and other parts of XML that aren't simple text are referred to as "markup."
