I want to use VA Snippets in the context of C# XML documentation. E.g. I defined a snippet with the shortcut 'xmlnull' for the code '<see langword="null"/>'. I can choose the snipped from the context menu. I can also use the shortcut somewhere in the code, BUT in the context of C# XML documentation (between <summary> and </summary>, for example) the shortcut does not work.
Most VA Snippets are never suggested in comments, since comments are "free text", so you do not want VA trying to insert an "if" or "for" block every time you typed the English words "if" or "for".
Shortcuts that start with "/" work in comments, e.g. "/c" or "//f".
