A position can consist of one number, or two divided by a non-digit, e.g. a colon. The first number is typically a page number in a printed dictionary. The second number may help to order several lemmas on the same page.
Structural changes to the lemma rely on the 'focus'. The focus is indicated by buttons that are gray rather than white. The focus is selected by clicking on a button. Clicking a button that already has the focus removes the focus.
A lemma consists of zero or more meanings, optionally labelled by a rank. For each meaning, there are zero or more uses. Each use is defined by a sequence of other elements, namely hieroglyphic, transliteration, translation, form, comment, alternatives ('alt'), and optional alternatives ('opt'). The latter two again consist of zero or more uses.
