Right now to refactor ANYTHING, I have to hover the mouse over the identifier or function and click the ever so small down arrow icon that appears seconds later. I think it would be more convenient and much faster to add this very same menu to the 'right click' context menu of Visual Studio. Simply add a sub-menu inside of the context menu with all the options needed when you right click a variable or function name.
if you are using VC6 you can add a VAssistX menu manually, otherwise you should already have one. personally I use alt-a, r to open the refactoring sub-menu.
allowing a keyboard shortcut to bring up the hovering refactoring menu is in the list
Keyboard access to refactoring menu is available in build 1540 but requires reset of VS.NET and VS2005. (Reset is not required if you do not need the RefactorContextMenu command.)
