The Check Spelling dialog appears if a word requiring your attention is detected and will list words detected as misspelled in the Not in Dictionary field. You can use the dialog to specify whether the word should be ignored or changed.
Change to field: Contains a word which will replace a misspelled word when you select the Change or Change All buttons. You can enter a word in the Change to field by typing, or you can select one of the suggested replacements from the suggestions list.
Ignore button: Causes this occurrence of a misspelled word to be skipped. If the same misspelled word appears later, it will be reported.
Change button: Causes the reported word to be replaced with the word in the Change to field. Only this occurrence of the reported word is replaced. If you want this and all following occurrences of the word replaced, select the Change All button.
Ignore All button: Causes this and all further occurrences of a misspelled word to be skipped. You might use this button if the word reported as a misspelling is actually spelled correctly. If the word is one you use frequently, you may wish to ignore it permanently or add it to the dictionary by selecting the Add button.
Change All button: Causes this and all following occurrences of the reported word to be replaced with the word in the Change to field. If you want only this occurrence of the word to be replaced, use the Change button.
Add button: Causes the reported word to be added to the personal dictionary for the Dictionary currently selected in the Dictionary configuration dialog and displayed there in the list of Added Words. Use the Add button if a correctly spelled word you use often is reported as a misspelling (e.g., your family name). If the word is not used frequently, you may want to select the Ignore or Ignore All buttons instead.
Cancel button: Stops the current spell-checking operation.
Options button: Opens the configuration dialog to the Miscellaneous topic for spell checker options.
