These shortcuts are limited to two alpha numeric characters, and are entered in the input field immediately preceding the library, object, or member.
These shortcuts can be repeated en masse for all entries displayed within the relevant PDM screen via F13.
This reduces the time it takes to complete common tasks like assigning authority, changing object ownership and several other functions.
Some other quick commands include saving, restoring, displaying descriptions, deleting, changing, working with, running, changing text, finding a string, creating a program or service program, running a debugger, and comparing.
PDM also has a filter tool (currently F17) which allows a user to narrow their search parameters and limit results by object, object type, attributes, a size range, or by complete or partial text.
