feature size, and <B>user</B>, based on the value given by the
user to the <B>grid</B> command. <P>
In addition to changing the behavior of the box to mouse
button events, the <B>snap</B> command also changes the way
that <A HREF=distance.html>distance measurements</A> are
interpreted in commands that take distance arguments, such
as <B>move</B>, <B>copy</B>, and <B>stretch</B>. An integer
number with no other identifying units is interpreted as a
measurement in the current snap grid. All other measurements
must have an identifying unit: <B>i</B> for internal units,
<B>l</B> for lambda units, and <B>g</B> for user grid units
(as well as the usual metric units). Even when <B>snap</B>
is set to the larger lambda or user grids, it is possible to
move the cursor box to finer grid positions from the command
line. See the reference page on
<A HREF=distance.html>distance measures</A> for a complete
description of distance values. <P>
Historically, in addition to changing the behavior of the box
to mouse button events, the <B>snap</B> command also changed
the way that <A HREF=distance.html>distance measurements</A>
are interpreted in commands that take distance arguments.
This behavior remains the default for backwards compatibility.
The <B>units</B> command overrides this behavior and allows
<B>snap</B> to control only the box positioning behavior,
independently of how unsuffixed values are parsed by the
interpreter. <P>
<B>snap</B> with no arguments returns the current snap grid
type. <P>
