The "Spell Checking..." command can be invoked 2 ways:
By selecting Extra->Spell Checking... from the Menu bar
By clicking on the toolbar.
Spell Checking your document is controlled through a dialog box.
In this example, the first mispelled word KWord found, was "KWord". It is currently suggesting "Kword". The complete list of suggestions is in the box labled "Suggestions".
From here you have eight options:
Replace - Replaces the current word with the suggestion. Only replaces this occurance.
Replace All - Replaces all occurances of the current word with the suggestion.
Ignore - Do not make any changes to this occurance. Ask me if this work appears again.
Ignore All - Do not make any changes to this or any other occurance. Do not ask me about this word again.
Add - Add the current word to the dictionary. STUFF!!!
Help - Get Help. STUFF!!!!!
Stop - Keep the current changes, but stop any further checking.
Cancel - Undo any changes made from this autocorrection.
When the entire document has been checked, KWord will return you to editing your document.
