3.1 Manual entry formatting

All the entries we have seen thus far have been simple math objects. However, it is possible to change the format of an individual entry by using the form:

*object arrows

This allows complete control over what object is placed in the entry, overriding any spacing and other conventions for the entry. This was how the frame was obtained in the figure in section 1.2.

A simple use of this is to insert text in entries using \txt objects just like labels as described above in section 2.2:

\xymatrix{
 *\txt{A very long and stupid\\program}
  \ar[rr]^-{\txt{weird\\arrow}}
 &&*\txt<2pc>{Com\-pli\-cated\\Code}}
