I gotta try the castle thing cause I'm not sure what you'r talking about.
About the red archer controls. If you get it working on the left side, it's almost the same in this side. The delete key I always used was the one over the direction arrows bellow "insert" and next to "end" (I wasn't sure which key to use and ended up with that one) I haven't tried the one "delete" in the num block and keep in mind "backspace" is not "delete" even though they can do a lot of similar things in other apps.
Thanks for the feedback!!!
