MenuRighter
MenuRighter is a utility that lets you add almost any “classic” menu control – such as the Edit menu or the Freeze Panes button – to any right-click menu. So, if you still remember where Goal Seek was in Excel 2003, it can be just a right-click away. It was featured by Debra Dalgleish on her Contextures Blog.
FaceId Viewer
This is an addin for determining FaceId numbers in Excel. It works for all versions of Excel that have classic menus, from Excel 97 to Excel 2003. It’s been recommended by a few folks, including Dick Kusleika of the Daily Dose of Excel.
