How to adjust gain to multiple clips at once in ProTools

Now there is a clip gain feature in ProTools, but do you know how to adjust the gain of several clips at once? Easy! Select all clips you want to adjust, then hold Control+Shift (on Mac) and use the mouse scroll button up or down.

And do you know that you can keyframe the clip gain as well? Use the mouse right click on the clip, Clip Gain/Show Clip Gain Line. Then use the usual Command+Click and Option+Click to add or delete keyframes, and tweak the gain line. This is in total independence to the track volume and its automation.
