I am trying to modify the New Document choice Slides_Beamer for my use. I cannot find such (light-blue) id tags such as authorid, subtitleid, instituteid etc. Where are they to be found? or how are they to be entered? And what is an msiframe?
Also, where can I find the tag form minpasses : 4 ? Why 4? is this a standard number for all files constructed from Slides_Beamer?
Also , how I can get, install, and use other Beamer shells besides "Madrid"?
