""Hi Eric,

For what it's worth I use the "x" key for delete.
Close to the left and easy to remember...

Marc""

Me too! I got it from blender, as well as space to maximize view or revert to 4 views, and also A to unselect, H to hide, L to select all curves. Speeds up a lot of the common operations.
I also assigned:
Shift+A to tag Grid Snap
Shift+S to tag Straight Snap
Shift+D to tag Object Snap

So while am moving/scaling/rotating something I can tag between all three. Without interrupting my work flow.

lol sometimes I get to where I want to be without realizing it, so I end up doing the same operation twice.
