During board design you will often want to move existing routing. This process has been greatly simplified in Altium Designer 6.0. When you drag a track segment the angle to adjoining track segments is preserved, maintaining the routing quality. This capability is enabled by turning on the Preserve Angle When Dragging option in the PCB General page of the Preferences dialog. A track segment is dragged (remains attached to the segments at either end) if it is selected before you Click+Drag. You can also use the new Ctrl+Click+Drag shortcuts to drag without first selecting.

With this option enabled you can also create new segments by dragging the end handle on a track segment – a new track segment is added, maintaining the horizontal/45/vertical behavior. To inhibit the add-segment behavior, hold the Alt key before performing the drag operation. The new dragging method obeys the Ignore Obstacle and Avoid Obstacle routing modes (use the Shift+R shortcuts to cycle through the modes).
