\ddanger Notice that the unit names in dimensions
are not preceded by backslashes. The same is true of other so-called
↑{keywords} of the \TeX\ language. Keywords can be given in uppercase letters
or in a mixture of upper and lower case; e.g., `|Pt|' is equivalent to `|pt|'.
The category codes of these letters are irrelevant; you may, for example,
be using a |p| of category~12 (other) that was generated by expanding
`|\the\hsize|' as explained in Chapter~20.
\TeX\ gives a special interpretation to keywords only when they
appear in certain very restricted contexts. For example, `|pt|' is a
keyword only when it appears after a number in a \<dimen>;
`|at|' is a keyword only when it appears after the external name of a
font in a |\font| declaration.
Here is a complete list of \TeX's keywords, in case you are wondering about
the full set: |at|, |bp|, |by|, |cc|, |cm|, |dd|, |depth|, |em|, |ex|,
|fil|, |height|, |in|, |l|, |minus|, |mm|, |mu|, |pc|, |plus|,
|pt|, |scaled|, |sp|, |spread|, |to|, |true|, |width|. ↑↑{reserved words}
\ (See Appendix~I for references to the contexts in which each of these is
recognized as a keyword.)
