We've used 3 methods.

In '07, we used the user-byte feature to display the autonomous mode in disabled, and indexed the number up or down using buttons hooked to i/o.

In '08, we used the remote control.

In '09, we used the two throttles on our tankdrive joysticks. One was distance, the other angle (fed back through the driver station LCD).

Right now, we've also prorammed a simple count-up / count-down on driver joystick button press so we can use the '07 method on the new control system with feedback through the 2010 driverstation user messages screen. It updates using the same LCD library the '09 one did.
