+\chapter{Capsule summary \linebreak of commands}

+This section contains one-line descriptions of the primitive \TeX\

+commands and the \TeX\ commands defined in \plainTeX. These include both

+We've omitted those commands that are only intended for internal use

+\plainTeX\ definition (\knuth{Appendix~B}).

+Note that ordinary characters

+such as `|a|' or `|6|' are also commands, and indeed the most common

+ones \seeconcept{character}.

+To keep the descriptions brief, we've adopted

+\li An asterisk in front of a command indicates that the command is primitive,

+^^{primitive//command} i.e., built into the \TeX\ computer program

+\li The words ``music'', ``punctuation'', ``function'',

+``symbol'', ``relation'', ``delimiter'', or ``operator'' in a command

+description imply that the command is only legal in math modes.

+\li The verb ``display'' applies to information

+that \TeX\ sends to the ^{log file}, unless otherwise indicated. If

+|\tracingonline| is positive, \TeX\ also sends that output to the

+terminal. We use the noun ``display'' to refer to math displays (see

+\xref{display math}), i.e., material between |$$|'s.

+\li The phrase ``produce $x$'' indicates that the command will typeset

+$x$ and put the result in a box.

+We sometimes omit ``produce'' when the omission is unlikely to

+cause confusion. For example, we describe |\alpha| as ``math Greek

+letter $\alpha$'', not ``produce the math Greek letter $\alpha$''.
