or commands, are what you use to make TeX do what you want it to do. Here is a list of the 960 or so control sequences of primitive and Plain TeX which I found on the Internet: csname.tex
. (Original file here.
For those who aren’t interested in typesetting mathematics I made a shorter version with the math-related commands taken out: csname-text.tex
‘csname-math’ contains all the missing math commands: csname-math.tex
The file ‘keywords’ contains some other things worth knowing about: special characters, keywords, dimensions, catcodes: keywords.tex
If you look at ‘csname’ you will see that about a third of the control sequences are primitives, i.e. they are built into the TeX program. The remainder are defined in the file
plain.tex (see here →, or search your TeX installation).
1. sets up code tables:
2. allocates registers:
\toks, input streams, output streams, math families, languages, insertions
3. sets parameters (e.g.
4. loads information about fonts
5. then come text macros, e.g.
\centerline, tabbing macros
6. macros for math
7. macros for output e.g.
8. hyphenation and everything else.
This list is from Appendix B of the TeXbook, which begins with a table showing commonly used Plain TeX control sequences with an example of their use, followed by a description of the macros contained in
Some macros are used as auxiliary macros in the construction of other macros, e.g.
\textindent which is used in
\joinrel, which is used to join math symbols together to make new ones, e.g.
\bowtie is constructed like this:
The private macros (those with ‘@’ in them) are also auxiliary macros used by
\@foot are used in building the
\m@g is used in the
\magnification macro. The idea of having ‘@’ in the control sequences is so that they will not be accidentally overwritten by user-defined macros.
David Bausum’s webpage (→) lists and gives definitions of all the TeX primitives. The appendix of ‘TeX by Topic’ also has a list of the primitives. ‘TeX for the Impatient’ has a ‘Capsule summary of commands’ which gives short definitions of the primitives and Plain TeX commands. If you read German ‘Einführung in TeX’ has a very full glossary of Plain and primitive TeX commands and the private macros too. (See below for links to these books.)
