CodeSpell for Visual Studio 2005 Manual
Custom Dictionaries
CodeSpell maintains two kinds of custom dictionaries, a local user set of words, and a per solution set of ignore words. This lets you have control over CodeSpell's error
detection.
User Dictionary
The user dictionary panel is launched from Tools|User Dictionary. This lets you edit a list of words that aren't counted as errors by CodeSpell. You can enter words directly in
this list, or add any word directly from the editor with the right click menu and pick Add Word.
Use the User Dictionary panel to edit your custom dictionary. These words will be used across all solutions.
Solution Ignore Words
The solution ignore words panel is launched from Tools|Solution Ignore Words. This is much like a user dictionary, but is limited to the current solution. The contents of this
list are kept in a simple text file right next to you .sln file called .sln.ignore. You can add ignore words in this panel, or by picking Ignore Word from the right click menu.
