I'm looking for a way to add some custom controls to some built-in
commandbars in Excel 2000. This is easy for the Worksheet menubar, but I
can't find the names or index of such built in commandbars as the shortcut
menu that pops up when the user right clicks, say, the y axis on an embedded
chart. Can someone suggest where I can find a list of Excel's Built in
commandbars and how I can intercept the right click event on the axis and
add my own controls to the resulting shortcut menu?

Thanks.
