I don't think this is a bad idea. Are there any objections?
I just checked and with the patch <MouseLeft> is generated when you
swipe your finger to the right on a trackpad (in line with the
inverted up/down movement). This feels weird...

Actually, on the Mac the Shift key is not used since when a "scroll
wheel" event arrives you also get to know "how much" the wheel has
moved and I use this to decide how many lines to scroll.
Is this sort of behavior available on other platforms? If so, I think
it is preferable over having to hold down a key to control how much to
scroll. I could submit another patch which includes the relevant code
from MacVim.
