on any manufacturers' shifters, the controls on the shifter control the same derailleur, either 'up' or 'down'. Right hand shifter controls the rear derailleur, left hand controls the front der.

Have you considered SRAM? Only one control on either shifter to control 'up' or 'down', plus the shift paddle and brake lever can be adjusted for closer reach.

Thanks for your help, seajay!
