If Do LaTeX Command Parsing is checked, Excalibur assumes that the file you are processing contains TeX/LaTeX commands.
Ignore \tt
Text instructs Excalibur to not spell
check words that are in the typewriter font.
Warn on Parsing Errors causes Excalibur to warn you if it thinks it found a LaTeX syntax error.
Use TeX Style Accents instructs Excalibur to use escape
sequences when making corrections that use accents. For example, when
making a correction it will represent the word naïve as
na\"{\i}ve
. If you type text into the Change To: box
using the extended character set, Excalibur will translate the text so
that it uses TeX style accents when making the correction. This is
useful if you don't remember the TeX sequence for a particular
accent.
This option also affects how Excalibur copies text from the suggestion list to the Change To: box. Words always appear in the suggestion box using the extended character set. However, Excalibur will copy them to the Change To: box with TeX style accents so you can see how they will appear in the document.
Use Extended Character Set instructs Excalibur to use Apple's
extended character set when making corrections that use accents. For
example, it will use naïve instead of na\"{\i}ve
. Even if
you type text in the Change To: box using escape sequences,
Excalibur will translate the text into the extended character set when
making the correction. If no translation is available (for example,
the character c doesn't exist in Apple's character set) Excalibur will
insert the word unchanged.
