For Parallel routing of traces depress the key combination Shift + E prior to selecting a starting pad of a traces set. This enables the mode for blocking several pins. Selecting the pins will enable parallel routing window where you can specify the routing space .Specify the spacing and click on Accept button.

The pad that is closest to origin of the blocking rectangle is taken as starting point of the leading trace in parallel group. The leading trace may be routed and other traces will follow it parallel with specified spacing.
After arriving to final destination for the leading trace, it can be connected in normal fashion. When leading trace is connected, the next unconnected is taken as the leading and parallel routing continues until all in the bunch been connected or operation aborted by Esc.

In some instances, it may be needed to narrow the spacing between traces to get through a tight spot. In such cases, routing of the leading trace and parallels may be terminated at any point with F4 key. With option “Allow T- connections” ON, lose ends of previously routed parallels may be grabbed in similar fashions as pads by blocking and new spacing (smaller or bigger) is applied.
