In Ardour, the Tranzport in has 3 different modes of operation termed "timeline", "scrub" and "shuttle". Timeline the data wheel scrolls the timeline in the editor window back and forth. Scrub the data wheel is used to scrub audio data back and forth. Shuttle the data wheel is used to control varispeed playback. Turning the data wheel clockwise increases the playback speed in a forward direction. Counter-clockwise decreases the speed and will reverse playback. Shuttle mode as several important features: While in Shuttle mode the actual playback speed will be displayed in the top right corner of the LCD as a percentage of real-time, ie. +100% is normal playback speed.

Releasing the SHIFT button will return to Shuttle mode at 0% speed. This combination of functions is very useful for quickly moving through an audio track and accurately locating points hit points.
