Hi Brian,
You would lose an important shortcut with that one: Ctrl+D is Copy Down
http://www.mvps.org/dmcritchie/excel/shortx2k.htm
You can create a macro, which has a little advantage over the shortcut
i.e. you are working with the mouse. I use toolbar icons to invoke the
macros but you could assign to shortcuts. I won't have likely created the
macros and toolbar icons had I seen the
Ctrl+PageUp and CtrlPageDown shortcuts.
Since I have other related toolbar buttons next to these, I can use the mouse
to go up or down through the tabs, and to delete sheets that have no event macros
with them. For your use, if you use ctrl+d, you don't gain much except
to change the shortcut from your right hand to your left hand don't know what
shortcut you would use in the other direction..
navigating to the Previous and Next sheets are described in BuildTOC
