That's a good idea. The help file does have them scattered throughout, but I will see what we can do about making a consolidated list. Also, pressing the ALT key will bring up some shortcuts for menu and ribbon items. But there are others that are kind of neat, here are couple to name some:
Click anywhere in the grid to use these...
Hold down z and scroll the mouse wheel to increase/decrease the amount of channels shown on the left side.
Hold down shift and scroll the mouse wheel to move the grid left/right
Hold down CTRL and scroll the mouse wheel to zoom in/out time scale
If you have an effect selected, hold down the s key and scroll your mouse wheel to change the start intensity of the effect. Hold down the f key and scroll the mouse wheel to change the final intesity of the effect.
