CodeSpell for Visual Studio 2005 Manual

File Spell Checking

CodeSpell can check an entire file at once, from Tools|Check Spelling. This will display a tool window of all spelling errors in the current file. Clicking on each line in the spelling panel will navigate you there.

The file spelling error panel has some memory, and will accumulate spelling errors in the files you open as you edit. This ends up being a convenient dashboard tracking all your current spelling errors, much like the Visual Studio compiler Errors panel keeps track of coding compilation errors.
