You can access spell checking operations from the main menu by clicking Format → Spell Check. Select one of the following operations:
Check from Cursor - Check spelling on the open file starting at the cursor's location. You can also use the spell_check command to perform this operation.
Check Comments and Strings - Check spelling only on comments and strings within the open file. Spell Check will start at the cursor's location. You can also use the spell_check_source command to perform this operation.
Check Selection - Check spelling only on text that is currently selected. The spell_check command also works for this operation.
Check Word at Cursor - Check spelling only for the word currently under the cursor. You can also use the spell_check_wordcommand to perform this operation.
Check Files - Check spelling on multiple files. You can also use the spell_check_files command to perform this operation. This will invoke the Spell Check Files dialog, which allows you to specify the files for checking. See Spell Checking Multiple Files.
When Spell Check is running and a word is found that is not in the dictionary, the Spelling dialog appears, prompting you for action.

The dialog shows the word not found and gives suggestions for a word replacement. Use the buttons on the dialog to perform the following actions:
Ignore - Disregard this word and continue spell checking.
Ignore all - Disregard all instances of this word in the selected range and continue spell checking.
Change - Replace this word with the text in the Change to text box and continue spell checking. You can use the suggested word or type your own word.
Change All - Replace all instances of this word in the selected range with the text in the Change to text box, and continue spell checking.
Add User 1 and 2 - Add the word not found to one of two custom dictionaries, after which spell checking continues. The first time new words are added to these lists, SlickEdit® Core creates new files in your configuration directory named userdct1.lst and userdct2.lst. See Spell Check Options for more information on custom dictionary files.
Undo Last - Undo the last spell checking operation. The focus is placed on the last word not found.
Options - Displays the Options dialog open to the Spell Check Options node. Options include specifying the default dictionary, ignoring uppercase words, and detecting repeated words. You can also access these Spell Check Options from the menu item Format → Spell Check → Spell Options or by using the spell_options command. See Spell Check Options for more information.
Skip File - When spell checking multiple files, use this button to skip checking in the current file.
The Spell Check Files dialog is used to specify multiple files for checking, and always does a language-sensitive spell check. For HTML, markup that is not literal text is ignored. For source languages where color coding is provided, only comments and strings are checked for spelling. To access the Spell Check dialog box, pictured below, from the main menu click Format → Spell Check → Check Files (or use the spell_check_files command).

In the Files text box, enter one or more files separated by spaces. Wildcards may be used (for example, *.html or *.c). You can use the Browse button to the right of this text box to choose a directory. There are two file options available:
Recurse subdirectories - If checked, wildcard file specifications in the Files text box will process subdirectories recursively.
Include project files - If checked, all project files are checked for spelling.
The Buffers list box lists the open buffers that will be spell checked in addition to the directory specified.
