What exactly happens if you don't add the keyboard events?
Upload your .capx and I'll see what I can do. EDIT: Tomorrow.
Hopefully I'll be able to explain the steps to you.
Use sub-events when you need to use the same event multiple times.
Put your events as subs on groups to add them to the group.
I used two different animations for the left and right animations because I made that prior to the r69 release. You can use the mirror property.
