How the headers are sorted

A card heading can be both a word and a phrase. There can be any number of spaced between the words forming a phrase. However, there will be only one space displayed when it comes to displaying a card. A space between words is accounted for when sorting the Word List.

A single card can have several headers. If you'd like a card to have several headers, type all the headers first (each heading must begin a line), then the card body according to the technique described above. All headers are shown in the overall Word List (each heading in its own place in alphabetical order); click anyone and the card body will be displayed.

The overall Word List can display words in different languages at the same time; both card and subentry headers are displayed. Each language's words are sorted according to "natural" dictionary order (i.e. alphabetical); all cyrillic letters are considered to follow all latin (x,y,z,а,б etc.).

Certain non-letter characters are also accounted for when sorting. Among these are colon, -, . (fullstop), ' (apostrophe), _, / (slash) etc.

You can use brackets in the heading to mark its alternative part, braces – to mark its unsorted part. It is impossible to use square brackets ([ ... ]) in the header.

Double braces mark a comment excluded from the dictionary text.

The use of #, @,<,> is disallowed; also forbidden are ~, ^ (you can use them in subentry headers, though).

Using "\" (back slash)

Back slash (\) can be used before any symbol in the card. 
If back slash is used before a symbol in the card it means that this symbol is used as a text symbol, not as a special symbol. In this case back slash will not be seen in the card.
If you want back slash to be seen in the card put double-black slash (\\).

You can not use #,@ symbols in card headings (except subcard headings).

You can not use  ~, ^ symbols in the first heading of a card. But you can use them in other headings, e.g.:

card

green ~
