.SH DESCRIPTION
In order to make menu selections visible on older terminals without
highlighting or color capability, the menu library marks selected items
in a menu with a prefix string.
-
-The function \fBset_menu_mark\fR sets the mark string for the given menu.
-Calling \fBset_menu_mark\fR with a null menu item will abolish the mark string.

+Calling \fBset_menu_mark\fP with a null menu item will abolish the mark string.
Note that changing the length of the mark string for a menu while the
menu is posted is likely to produce unhelpful behavior.
-
-The default string is "-" (a dash). Calling \fBset_menu_mark\fR with
-a \fBNULL\fR menu argument will change this default.
