 @item \mid
- at domain.hid} (relation)
+Single-line vertical bar @U{2223} (relation).
+Synonym:@tie{}@code{\mvert}.  Similar: @code{\vert} and at domain.hid{|}
+produce the same vertical bar symbol but without any spacing (they fall
+in class ordinary) and you should not use them as relations but instead
+only as ordinals, i.e., footnote symbols.  Related: the synonyms
+ at code{Vert} and at domain.hid{\|} produce double-line vertical bars.
+
+A typical use of @code{\mid} is for a set @code{\@{\, x \mid x\geq 5
+\,\@}}.  For the divides relation use at domain.hid}.  
+
+For absolute value you can use the @file{mathtools} package and add
+ at code{\DeclarePairedDelimiter\abs at domain.hid@}} to your
+preamble. This gives you three command variants for single-line vertical
+bars that are correctly horizontally spaced.  If in the document body
+you write @code{is about $\abs*@{\frac at domain.hid@}@}$} then the height of
+the vertical bars will match the height of the fraction, whereas with
+ at code{\abs at domain.hid@}@}} the bars do not grow with the height of
+the argument but instead are the default height and @code{\abs[@var{size
+command}]@{\frac at domain.hid@}@}} also gives bars that do not grow but are
+set to the size given in the @var{size command}, e.g., @code{\Bigg}.
+(Putting @code{\DeclarePairedDelimiter\norm at domain.hid@}} in your
+preamble will produce three similar commands for double-line vertical
+bars.)
 
 @item \models

+Double turnstile, short double dash; models, or satisfies @U{22A8}
+(relation).  Similar: long double dash at domain.hid}.

+Minus or plus @U{2213} (relation).
