I have an Add-In I Created for our users here, it works great, installs perfectly, all is good, so far. I would like to add some existing Excel buttons that don't appear in the ribbons to be on my Add-In ribbon, but I can't see how to do that, unless I write little macros to invoke the command associated with the button and then attach that macro. Am I missing something? Can I not add buttons for existing Excel functionality (e.g. Select Visible Cells and Close, etc.) Thanks!
