In Microsoft Word 2008, there’s a menu called “Work”. At first, it contains only one item, “Add to Work Menu”. If you select this, the location of the current document is permanently added to this menu. There is no obvious way to rearrange or delete items on this list, or inform Word that they’ve moved to a different folder.
The only way to modify this list is to open the “Customize Toolbars and Menus” screen and bind a key or menu item to “ToolsCustomizeRemoveMenuShortcut”. When you run that command, the next menu item you click on will be deleted. Any menu item, in any menu, and the only indication that you’re in this mode is a different cursor that reverts to normal when you open a menu…
The work menu was apparently in Office 2004, too, but I never noticed it. Apparently the only difference was that there was a default keybinding for the magic command, which was removed for 2008 because people sometimes typed it by mistake and had no idea what had happened to their menus.
How does Microsoft feel about this? Read this thread. Short version: “stupid things only get fixed if more than 1000 people use the Send Feedback form and describe the problem precisely enough for the automated system to collate them together”.
