Selected files
==============

   Many of the commands work on the current set of "selected" files.

   * If marks are not being ignored, and there are any files that are
     marked, they constitute the set of selected files.

   * Otherwise, if the cursor points to a file, that file is the
     selected file.

   * Otherwise, if the cursor points to a directory, all the files in
     that directory that appear in the buffer are the selected files.

   By default, marks are always in effect.  You may change this,
however, by setting either of the variables `cvs-diff-ignore-marks' or
`cvs-default-ignore-marks', which define whether marks are in effect by
default for the diff commands and for the rest of the `*cvs*' buffer
commands, respectively.  Both are `nil' by default.

   In addition, you may use the command `cvs-mode-toggle-marks'
normally bound to <T> to toggle the use of marks for the following
command.

   This scheme might seem a little complicated, but once one get used to
it, it is quite powerful.
