Accented characters

There are two kinds of accented characters:

• Those with the same canonical pattern as International Morse Code (é, è, ç, ñ, þ ).
• Those that either don't have canonical patterns, or have canonical patterns that were hijacked by MouseCode to make it easier to use for US English (ü, ä, and ö in particular, since they had nice, short 4-element patterns and are rarely used (and almost never required) by American English).

Generally speaking, lowercase accented characters are digraphs that begin with F
Uppercase accented characters are digraphs (trigraphs) that begin with XF

Acute accent

é uses the canonical pattern, which (conveniently enough) happens to be identical to the digraph FE (or for uppercase, XFE)

á,í, ó, ú, and ý are entered as the digraphs FA, Fi, Fo, FU, FY (or, if capitalized, XFA, XFi, XFo, XFU, XFY).

Grave accent

è uses the canonical pattern « .-..- », which happens to correspond to the digraph LT

à, è, ì, ò, and ù can be entered as the digraphs F«-.»A, F«-.»E, F«-.»i, F«-.»o, and F«-.»U
(think: "- ." resembles a grave mark)

French-speakers might find the following alternate pattern easier to remember for ù: FoU

Diareses/umlaut:

ä, ë, ï, ö, ü, and ÿ are entered as the digraphs (technically, trigraphs) FiA, FiE, Fio, FiU, and FiY
(think: "i" is « .. » )

Tilde:

ñ has multiple patterns. Pick the one you can remember the most easily:

Its canonical Morse code pattern: « - - . - - »

The digraph FN (think: "foreign N")

The trigraph F + « .-.- » + n (think: .-.- resembles ~)

The letters ã and õ can be entered as F + « .-.- » + a and F + « .-.- » + o

Circumflex:

The letters â, ê, î, ô, and û can be entered as FRA, FRE, FRI, FRO, FRU (think: FRench, or F + « .-. », which resembles '^')

Other Letters:

å, ß, ç , ø can be entered as the digraphs FoA, Fss, FC, and F0 (zero).
