My understanding on the keymap is that it will pass hotstrings only when you hit the base key. So you can't have a "2" and "shift 2" keymapped, I think. I was going to use the keymaps for those things that require targeting but for things like totems and thunderstorm I was going to use a global and castsequences where required.

I have an xkeys but I haven't started to integrate it into the new setup. I am going to try it out on the g15 first and see if that is comfortable. If the G15 is not feasible then I will redo the xkeys for this setup. It needs redone anyway because of totem and paly changes.

I think the biggest obstacle for this setup is making sure you don't overlap any key usage between the key map and normal passed combos. I plan on using multiple mods per key for the globals (i.e. general totems) as that is what I did before and it worked fine. I used an excel layout of the xkeys, that I made myself, printed out a few copies and started penciling in key combos. There are enough normal combos to fill out both layers on the pro if you want to. Since you have a laptop you can make good use of all the NUMPAD characters. That is 15 keys (not counting enter and numlock).

I will get to do my own extensive testing starting in about 8 hours from this post. Maybe I will move all the functions to the xkeys for playing the paly and shamans. Then when the 5th shaman is ready I can play them all on a standard keyboard.

Good luck.
