Look at an example

Before writing your own style file, it may be useful to take a look at some standard style files. For instance, you may load book.ts using File→Load (no path is necessary here, since the style directory is included in the default file path).

After loading book.ts, you will see many function and environment declarations (these declarations are visible, since style files are written in “preamble mode” (see Options→Mode)). Some more declarations are contained in the files basic.ts, list.ts, theorem.ts and program.ts on which book.ts is based. These files respectively contain basic, itemize-like, theorem-like and programming environments.
