This was my issue. I bought a naga, tried it and ended up putting it on the floor next to my desk in utter frustration. "Why can't it be just another damn mouse button!?" I use healbot myself. But the only way I could seem to get it to work was by creating a new macro and keybind for my regular bars and then tie it to healbot that way. I admit this is a while ago and a lot of updates have happened since. But I didn't have to do that with my logitech mouse? I just plugged it in and the extra buttons were recognised easily. I'm not the most tech savvy person in the world and just trying to set up the naga with healbot felt like a losing battle.

I agree that if you want to bind the side keys to mouseover type macros, that would be a pain. But, I'm a huge fan of Grid+Clique and the Naga. The solution is pretty simple: put things on the Naga side buttons that you don't need to use via mouseover.

As a shaman, I use Wind Shear, Water Shield, Earthliving Weapon, Totem sets, Mana Tide, Mana Pots, etc. Frees up a lot of out of the way, hard to hit keybinds and puts them right at your mouse thumb, which for me was otherwise being unused.

I heal with this mouse using vuhdo. All my heals are bound to the num pad buttons and act as mouseover macros. You don't need to write macros for each button with this set-up. You just go into your key-bindings and arrange them so the number pad is bound to the vuhdo key listing. I'm not in front of my computer so it's a hard to explain. It's a very simple process though and can be done through the vuhdo ui.

For my dps/tank alts I have it set up with bartender. I don't use mouse over macros for these classes. I can set it up so that the number pad on the mouse triggers cds and other spells that target myself.

The addon BindPad completely fixes this problem. You make the [@mouseover] macros in the BindPad interface, bind them (I chose to bind them to the NumPad), close the interface, and there you go - hidden keybinds that work with the Naga and don't take up macro space. I still use Clique to bind Left/Right/Middle click when using Grid.

The addon is tiny and easy to use. I would recommend a Naga to any healer. It was a godsend to my priest with her 72million (or thereabouts!) spells.

You're right. If you want to hit a number key on the mouse to trigger a click heal with Grid/Vuhdo/Healbot. Honestly, it never occurred to me to try that. :)

Thinking about it, I'd only need 6ish character-specific macros to heal like that on my Holy Pally. Not too bad considering right now I have only one macro for that character: beacon mouseover. I used to have two before they removed Sacred Shield.

I use Vuhdo and use the modifier keys to select heals like I did before the Naga. I use the Naga buttons to do things I normally would have used number keys for. I've been healing with a Naga since the original one shipped and don't plan on going back.
