+\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 $\alpha$''.
