Theorem.
Is this a recent addition to LyX? I'd like to insert theorem-like
environments this way, but I can't do it. E.g., what "AMS class" do I have
to use, to see "theorem" in the drop-down list?
I think I was using it in LyX 1.3.x; I know I was in 1.4.x. In Document
-> Settings... -> Document class, pick from: article (AMS); article
(AMS, sequential numbering); article (AMS, unnumbered); or (if you're
really wordy) book (AMS). The differences among the article classes
have to do with how theorem-like things are numbered. All three have
theorems, lemmas, corollaries etc. on the environment list.
The four AMS layout files load a bunch of include files that define all
these things and tell LyX how to display and number them. Richard Heck
indicated that, in LyX 1.6, we'll be able to plug those modules into
other classes.
