I have a lot of recorded macros for MS Office to automate some of the things I do frequently (ie: setting up a large document with page numbering, guttering for binding, two-side printing,, multiple sections, alternate page footers and headers for each section, title page, table of contents page etc with the click of one button on the toolbar).

I also have custom styles that I use. Having to recreate all those Styles and macros can be a real nuisance.
