This file contains ED commands used to configure the ED text editor, assigning the default function key options. Key assignments can be customized by editing this file. These scripts allow pattern matching with commands that do not normally support pattern matching.
SPat adds pattern matching to single -argument commands.
DPat adds pattern matching to double-argument commands. After DPat and the command name, enter the two arguments separated by a space, using the wild cards required to poduce the results needed. Like the CD command, the PCD script changes the current directory. However, PCD also remembers the directory from wich you are changing so you can return with out entering the etire path . Each shell has and independant PCD memory.
