How would I change subsections from being name 1.1, 1.2 to 1a, 1b? And are there any good templates for problem sets/college homework?
Changing subsection from numeric to alphabetical
You can put the following in your preamble (Document -> Part -> Show preamble
). Make sure to paste it in by doing Edit -> Paste from -> TeXmacs
.
<assign|display-subsection|<macro|nr|<the-section><number|<arg|nr>|alpha>>>
