Deleting multiple channels at once?

Originally posted by ChrisL1976 one at a time is the only way I know of right now.

After importing a sequence, then modifing it to fit my display, I want to delete the channels from the imported sequence.  So far I've found that my right clicking the channel it brings up a delete channel option. that works fine but I can't seem to delete more than one channel at a time with the right mouse button.  Channel editor just might be the key, but I've haven't figured it out.  I've tried using the shift and control keys to select more than one channel, but that doesn't seem to work.
