Note On large documents, spell checking the entire content may take a lot of time.
- Default language
The default language combo allows you to choose the language used by default.
- XML language attributes
Options in this subsection control the way the attributes lang and xml:lang change the language used for check spelling.
Obey "lang" and "xml:lang" attributes - when checked the value of these attributes is used as check spelling language inside the content of the element where they are present.
When these attributes are missing the language used is controlled by the two radio buttons. The two options are to Use the default language or Do not check the spelling.
- XML spell checking in
These options allow the user to specify if the spell checker will be enabled inside Comments, Attribute values, Text and CDATA sections.
- Case sensitive
When checked, operations ignore capitalization errors.
- Ignore mixed case words
When checked, operations do not check words containing case mixing (e.g. "SpellChecker").
- Ignore words with digits
When checked, the Spell Checker does not check words containing digits (e.g. "b2b").
- Ignore Duplicates
When checked, the Spell Checker does not signal two successive identical words as an error.
- Ignore URL
When checked, ignores words looking like URL or file names (e.g. "www.oxygenxml.com" or "c:\boot.ini") .
- Check punctuation
When checked, punctuation checking is enabled: misplaced white space and wrong sequences, like a dot following a comma, are detected.
- Enable auto replace
Enables the "Replace Always" feature.
- Allow compounds words
When checked, all words formed by concatenating two legal words with an hyphen are accepted. If the language allows it, two words concatenated without hyphen are also accepted.
- Allow general prefixes
When checked, a word formed by concatenating a registered prefix and a legal word is accepted. For example if "mini-" is a registered prefix, accepts "mini-computer".
- Allow file extensions
When checked, accepts any word ending with registered file extensions (e.g. "myfile.txt", "index.html" etc.).
- Suggestion
This option indicates the type of spell checker accuracy, which may be: "Favour speed over quality", "Normal" and "Favour quality over speed".
