Press and hold one of the character softkeys to see how to produce that character using a sequence of keyboard
keys. Esc and Shift+Esc may be used instead of the semicolon to cycle forward or backwards through the possible
interpretations of a given sequence.
A given character may be represented by a single dedicated Unicode code point such as Á (0xC1), or a
combination of code points such as Á (0x41+0x301). Some characters have only one of these representations, others
have both. Enable "only single-code characters" (if available) to hide characters which do not have a single dedicated
code point, and block their keyboard key sequences.
Enable "lock focus" to make the focus automatically jump back into the text entry box after each softkey click.
