Finer control of keyframe edits @ Adobe Premiere Pro CS5

This feature improves the control and precision when dragging keyframes in a confined space. For example, audio gain values can jump dramatically in coarse amounts when dragging an audio volume rubber band or keyframe in the confirmed vertical space of an audio track. To more precisely set the gain value, drag while holding down modifier keys to yield finer control of the rate of change in the parameter value. Hold down Option (PC: Alt) to change the numeric value by 1; hold down Command (PC: Ctrl) to change the numeric value by 0.1.
