I did an Introduction to LaTeX for Linguistics at McGill today.
If you want to see the files that went into making it, you can download all of the presentation files. It is a beamer presentation.
Note: There was a problem with the display of the example of example numbering in the original version. Those who were present, and those who have a physical handout, know what I mean. It has been fixed here. Although I am not completely sure what the root cause of the problem was, changing the order of the includepackage commands in the preamble made everything work out.
In case it is interesting, I’ll also post my phtools.sty file, which is basically a package I wrote myself that just includes the other packages I usually use (in an appropriate order) and defines some common convenience macros I use. In there, I also refer to my syntaxarrows.sty file, which I wrote to help out when drawing arrows over a line of text. Both of those are just for informational purposes, you can think of them as unsupported alpha versions.
