D2 casting system

Anyone here know how to make the casting system similar to D2? Ok, let me explain a bit. In D2, pressing the hotkey will select the assigned spell to be cast when using either left click or right click. So I am wondering if it is possible to have this system in wc3 too rather then you have to keep on pressing the hotkey to cast the spell.

Thus the effect will be something like maybe pressing C for carrion swarm will highlight the spell and whenever you left click, the unit will cast carrion swarm. You do not have to repeatly press C just to cast multiple swarm.

using the hotkeys ain so bad =P.... but anyway, I doubt you can, with triggers there is just few keys that you can use, like the up arrow key.... that woudnt be so useful would it?

Maybe you could make a modified version of my spellbook system.

I don't think you Spellbook system is revolutinary or creative? I just don't like the annoyance of having to click like 80 times just to find a spell. I mean imagine being in a heated battle and your clicking through the spells, as your getting killed.

It was just a suggestion.

Sum it up: No. There are ways similar to do it, but no actual 'push button and do blah', aside from arrow keys.

Well, maybe if you added... hrmm, that spellbook system just needs work. I'll let you what need improving. Give me a few hours/minutes.

Hmmm, if it is rather hard to make, then I think I can do away wif it. I can just make do with the simple way. Currently I am just using the item ability of the lightning orb. Thus I have a unit that casts whatever spell that I equiped with when you give it a command to attack. Of cuz this will not allow orbs or mask of death to be used. Also, ability like life steal and barrage and some other spells cant be used too. Actually it would be nice if someone could provide a list of what ability cant be used when one of the ability under this class is being learn by a unit.

To name a few, those orbs ability, life steal and barrage. Pls correct me if I left out any.

Oh come to think of it, I wonder if my idea will work. For example, you have a unit/hero with seven ability(without getting rid of any of the command), each spells will have its hotkey right. I wonder if we could create seven smiliar unit, with each of the unit having one of the different ability working.
Thus, my idea will be having a trigger that determine which ever hotkey you press, you will have your unit replace with the correct unit that has the passive ability to cast that spell you have selected.

I cant explain well, thus here is my example.

You have a unit/hero with 7 ability. Carrion swarm, war stomp, flame strike and so on.(you get the idea dun you). So here the hotkeys will be C, T, F and so on. Using my above idea, is itpossible to have trigger detect wat hotkey we have press and replace the unit with the approtiate "clone" of the unit with the right passive ability?
