On ISBoxer's website it states "create auto-assisting Action Bar hotkeys..."

[Sam DeathWalker]

Isboxer converts its stuffs to normal wow macros, which are completly allowed. You can see the end result in

World of Warcraft\Interface\AddOns\ISBoxer\Isboxer_Characte r-(whateveryurcharacteris)

For example here is a partial of one of my guys, as you can see nothing is out of the ordinary:

isboxer.SetMacro("","ALT-CTRL-SHIFT-H","/target Samdeathwkzz\n/cast Chain Heal\n",nil,nil,nil,1);
isboxer.SetMacro("","CTRL-SHIFT-X","/cast Runic Mana Potion\n",nil,nil,nil,1);
isboxer.SetMacro("","ALT-CTRL-H","/script ToggleCharacter(\"PaperDollFrame\")\n",nil,nil,nil ,1);
