Just as you can use Word’s spelling checker to check only
selected text, you can also turn off spell checking for selected text. For
example, if you’re typing a block of VB code or a price list complete with
parts numbers, the spelling checker will probably go ahead and mark the entire
text as misspelled.

However, you can prevent the spelling checker from checking
this text altogether. Follow these steps:

  1. Select
    the text you don’t want Word to check.
  2. Go to
    Tools | Language | Set Language.
  3. Select
    the Do Not Check Spelling Or Grammar check box,
    and click OK.

Keep in mind that this procedure not only excludes the
selected text from spell checking but also from grammar checking and
AutoSummarize processes.
