The headword of a card can be either a word or a phrase. The words in the headword can be separated by any number of spaces. However, multiple spaces will be substituted by one space when the card is displayed in Lingvo. Spaces are taken into account when headwords are arranged alphabetically in the word list.
One card may have several headwords. If you want a card to have several headwords, first type these headwords (each starting a new line), and then type the body text of the card. All the headwords will be shown in the word list (each headword in its own place in the list). Clicking any of the headwords will open the corresponding card.
The word list can contain words in different languages; these may be headwords of entries or headwords of subentries. Words in each of the languages are arranged in their "natural" dictionary order (i.e. alphabetically); Cyrillic letters follow Latin letters.
Hyphens (-), full stops (.), underscore (_), comma (,), and forward slash (/) are not ignored.
You can use parentheses to mark an optional part of the headword and curved braces to mark an unsorted part of the headword.
You can use any special symbols (like ~ or ^) in the headword text, but you must put a backslash (\) before each of such symbols. To use a backslash itself in the headword text, you must put double backslash (\\).
