The Zeus Quick Help feature can be used to search and load pages of the MSDN all from within the Zeus editor.
To configure this feature select the Quick Help panel from a given Document Type, pick the MSDN Help item from the list of Help Filters and add it to the list of Installed Help Files.
If you now open a text file of the same Document Type, you can place the cursor on the word and use the Help, Quick Help Current Word menu item to search for that word within the MSDN.
For example, placing the cursor on the GetLongPathName word within a text document and using the Help, Quick Help Current Word menu the following MSDN page is displayed in the help window:
ms-help://MS.VSCC.v80/MS.MSDN.vAug06.en/fileio/fs/getlongpathname.htm
