You can also use

    :w
    :e otherfile
    ...
    :w
    :e #

The pound sign expands to the "alternate" filename.  There is
only one alternate filename; it's the name of the file you were
last editing (i.e. ":n" makes the current filename become the
alternate filename).

Percent sign (%) expands to the current filename.

Both of these work for ":!" also.
