The Spell Check option in the Tools menu provides access to Help+Manual's spell checker and its configuration options. Full details of these options and the configuration settings are can be found in The Spell Checker in the chapter on the tools included with the program.

Note that Help+Manual supports live spell checking that marks incorrectly-spelled words as you type. Just select Spelling > Configure Spell Checker and activate the Check spelling as you type option.
