I have written a macro which uses Ctrl+r to run. I have no problems using
it on the computer that I created the macro on.

When I move the macro to another computer, I cannot use Ctrl+r to run the
macro despite the fact that Ctrl+r is mentioned in the macro and the Macro
Options dialog box also shows the Shortcut key as being Ctrl+r for the
macro!
There are no other macros on that computer.

Can someone please tell me how to setup Excel to use Ctrl+r to run the
macro?

Thanks!
