Ok, so many of you out there already know this and it may seem common knowledge to you, but I only personally figured this out a few months ago and therefore believe it should be shared.
So, you have trouble wall jumping eh? not because you cant angle yourself or because you don't know how to...but mabey your index finger and thumb don't tap forward and jump at the same exact moment :O !?!?!?! THERE IS A SOLUTION!!! Bind the secondary hot keys for forward and jump to two keys that are adjacent to each other, i prefer one being over each other like the <home> and <end> keys this allows you if situated vertically to tap both at once by using one finger angled at a angle parallel with the curvature of the earth in order to produce the perfect jump!
NOTE: I doubt we can macro this as if we could you could basically macro playing to the full extent I've tried some commands but no luck...but if anybody knows of any please feel free to chime in
