The Spell checker » Filters branch of Settings allows you to configure various options used for spell checking.
If this option is selected spell checking will occur automatically as text is typed. Unrecognized / misspelled words will be indicated by a dashed red underline beneath the word (as is common in other applications). Note: By default UltraEdit / UEStudio will not apply this to syntax highlighted files. To change this setting and support spell check as you type for a syntax highlighted file, add the following to the language definition line (e.g., /L3"HTML" ...) of the wordfile: EnableSpellasYouType
.
If this option is selected when Enable spell check as you type is enabled, right-clicking on a word indicated as misspelled will result in a list of possible spelling options. If you prefer, check the option Only if CTRL to display the list of suggestions only upon Ctrl + Right click. You can also specify a maximum number of suggestions to be displayed using the Display suggestions (max) control. Set to "-1" to display all available suggestions.
Any word less than the numeric value specified here (from 1 to 9) will not be spell checked.
