Adding Your Own Words
If you want to add a word to the spell checker's user dictionary, then you can use the integrated editor to perform a spell check using Tools->Spell Check (you cannot add words using the validator engine). When performing a spell check in the integrated editor, you will be given the option to add misspelled words to the user dictionary.
If Live Spelling is enabled, then misspelled words are underlined with red squiggly lines. These words can be added to the custom dictionary by right-clicking on the word and selecting the Add option from the context menu that appears.
Another option is to use the Custom Dictionary Tab in the Spelling Option Dialog (accessible from the Spell Checking Page in the Editor Options). Select the dictionary that you want to add words to then add the words using the Adds tab.
