Thank you, Charles. I didn't know that about templates, so thank you for pointing that out.

I have backups of my macros and customisations, but didn't want to import them because I think the macros are still in the template and/or the documents that use it, even though I can't access VBA and they are not listed in the list of macros. Some but not all of my old shortcuts and macros still work, and as the macro list doesn't show up in the keyboard customisation list I can't reassign shortcuts to them. I didn't want to import the macros again and find that I had duplicates of them in a particular template. Is there any way I can avoid that? (I also have shortcuts on my Quick Access Toolbar for some of the macros.)

Thank you for the links. I shall study them in greater detail when I have more time but I have a job that I need to get on with.
