+13. Spell check and dictionaries
+================================
+Since version 1.64, SlyEdit has a spell check feature.  Spell check can be
+started by the user with the Ctrl-R hotkey, or by the Edit > Spell Checker
+option in the DCT-style ESC menu (only available when in DCT mode).  For spell
+check, SlyEdit will check each word to see if it exists in the configured
+dictionary/dictionaries, and if not, it will prompt the user for a corrected
+version of the word.  The sysop can configure one or multiple dictionaries in
+SlyEdit.cfg with the dictionaryFilenames option.  Dictionary files need to be
+in the format dictionary_<languageName>.txt, where <languageName> is the name
+of the language - For instance, dictionary_english.txt for English.  Also, the
+dictionary filenames will be parsed and the language name will be used in the
+menu of dictionaries in the user options - The user is able to enable/disable
+the configured dictionaries for their own use for the spell checker.
+
+For the dictionaryFilenames option in SlyEdit.cfg, you can specify a comma-
+separated list of dictionary filenames.  The dictionary filenames are in the
+format dictionary_<languageName>.txt, where <language> is the language name.
+In this list, the filenames can be in that format, or just <languageName>.txt,
+or just <languageName>.  You can leave the setting blank to use all dictionary
+files that exist on the system.
+
+SlyEdit will search for the dictionary files in the following directories, in
+this order:

+2. sbbs/ctrl
