Dialog mode prompts for an input line, parses it into words, and performs

Readline is an enhancement for the input line. You may know it already from
the bash shell.

It allows to move the cursor over the text in the line by help of the

the history of previous input lines.

> \fB\-follow\fR "on"|"off"
Enable or disable resolution of symbolic links under disk_paths.
If disabled by "off" then symbolic links are added as link objects with
unchanged target address. If enabled by "on", then the link target gets added.
\fB\-follow\fR occasion[:occasion[...]]
Enable or disable resolution of symbolic links and mount points under
disk_paths. This applies to actions -add, -du*x, -ls*x and to -disk_pattern
expansion.
.br
There are two kinds of follow decisison to be made:
.br
"link" is the hop from a symbolic link to its target file object.
If enabled then symbolic links are handled as their target file objects,
else symbolic links are handled as themselves.
.br
"mount" is the hop from one filesystem to another subordinate filesystem.
If enabled then mount point directories are handled as any other directory,
else mount points are handled as empty directories if they are encountered in
directory tree traversals.
.br
Less general then above occasions:
.br
"pattern" is mount and link hopping, but only during -disk_pattern expansion.
.br
"param" is link hopping for parameter words (after eventual pattern expansion).
If enabled then -ls*x will show the link targets rather than the links
themselves. -du*x and -add will process the link targets but not follow links
in an eventual directory tree below the targets (unless "link" is enabled).
.br
Occasions can be combined in a colon separated list. All occasions
mentioned in the list will then lead to a positive follow decision.
.br
"off" prevents any positive follow decision. Use it if no other occasion
applies.

Shortcuts:
.br
"default" is equivalent to "pattern:mount".
.br
"on" always decides positive. Equivalent to "link:mount".
