Not sure if this totally answers the question, but there are two really good shortcuts - "Write To Current" (cmd \) and "Write To All Enabled" (alt cmd \)

First, you have to turn off "Link timeline and edit selection". This allows you to make a selection, but still independently move the cursor around.

Then, if you make a selection, no matter how long or short, across as many tracks as you want, then park the cursor anywhere up in the timecode bar at the top of the edit window, you can paste a snapshot of the automation from clips directly under the cursor to the entire selection. "Cmd\" just pastes the one parameter that is selected, "alt-cmd \" pastes ALL automation to the selection.

This works across multiple tracks, depending on how many you have selected, so you can copy a snapshot of the automation from all tracks of a scene to any other section of the timeline. This is an incredibly powerful function that surprisingly few people seem to know about. You don't need to use Preview, or disable anything, and it only pastes to the selection, so there are no issues of writing over the entire timeline.

If you like that, have a play with "Glide to Current" and Glide to all Enabled". Lets you change all automation parameters gradually, over whatever range you select, over as many tracks as you want.

Only available in HD, of course.
