<TAB> for <BACKTAB> the M300 Workstation Available to Purchase

In case you haven't read or thought enough about ways to define the function keys on the M300 Workstation, here is another possible set of definitions. These definitions stem from my frustration with the present lack of a TAB key for the OCLC Cataloging Subsystem; it seems as though I spend considerable time each working day with the right or left arrow pressed, waiting for the cursor to reach the middle of a line of text.
