To easily find these preferences in the list filter by searching for: spell

Default Language

Change this to use your preferred language in the spell checker by default (without selecting it from the list).

The value you put in here must match the name of the tdf file found in the App_Data\RadSpell folder

• en-US (english)
• fr-FR (french)
• de-DE (german)
  
• es-ES (spanish)
• th-TH (thai)

Selectable Languages

Change this to use your preferred ordered list of languages in the spell checker dropdown list.

Example: English: en-US, French: fr-FR, German: de-DE, Spanish: es-ES

Pattern: Name: code

NOTES:

• keep the list in the format of language name then colon then language code/filename
• separate different languages with a comma
• Changing the order of the languages in this list will change the order of the languages in the dropdown.

Provider

Must be one of

• Phonetic
• Distance

Change this to Distance if you encounter problems with a selected language.

Phonetic is best for western languages especially English.
Distance may be required to support some languages.

If you are using Distance then the Edit Distance preference value also applies.

Edit Distance

When using the Distance provider - increase this value to get more suggestions but with decreased performance. Does not apply when using the Phonetic provider.
