There are some on google if you search for them but they are from 1.0 and a little out of date. Only things that are different are things like, <st> doesnt work, added <se.1>, etc. Most of the stuff that works i have mentioned in the guide ha ha.
There was a really good up to date one that the admins posted on the beta forums, but it is lost in time now unless someone had saved a copy, or they decide to post it again!
I havent found a /use /item /itemname macro yet so i dont believe there is one yet, sorry :x
There isnt, because there are hotkeys (example, on ps3 if you press L1 you autorun and L3 to dismount) and commands like the actual mount/dismount icon that you can put on your hotbar, :x sorry!
