I put an EQ on all dialogue tracks.
First I apply a general lo-cut and a general hi-cut to all tracks. The hi-cut will be somewhere around 13k and the lo-cut somewhere between 80-125 Hz, depending on how it all sounds. I always use steep 24 dB filters.
Normally I work on HD, so I also use the automation preview to find the right EQ, and then write to all. I am almost always in touch mode.
If I am working on LE, I tweak the controls with the mouse, but I will probably be in latch mode, so it doesn't snap back all the time...
You can also press cmd+ctrl while clicking on a control, and then the parameter graph pops up on the track, so you can make quick general changes.
