Setting up ISBoxer for WoW is easier than setting up ISBoxer for RIFT. When you Export to Inner Space, ISBoxer creates an Addon for World of Warcraft that includes things like Follow and Assist macros that work for every character on the team -- you don't have to configure any in-game key binding for Follow or Assist. The only one you really have to set up is "Interact with Target" because it has no default and must be activated by the hotkey.
To get follow to work, turn on the ISBoxer Addon in the game, have Key Maps on, and press the ISBoxer Hotkey for Follow Me, which is Alt+F (noting that your in-game Alt+F will not activate if ISBoxer hotkeys are enabled, because ISBoxer's Alt+F hotkey will override it).
This is all explained and demonstrated in the
WoW Quicker Start Guide and the wow walkthrough video on the page (that's me in the video walking through follow, assist, interact with target, doing combat, etc). Really the only thing you're missing here is that you should go to this page and quickly run through it
