Event action abstraction and trigger control

I am thinking of abstracting Event action in order to make further alteration/implementation/maintenance easy since the project I am currently working on has volatile requirement. So I thought of the following concept. I created an implementation of IEventAction which ex. handles closing of planning in my application, I made IEventAction extends IEventAction so I can manage all EventAction using a generic collection; and using a factory, I will get the appropriate event by passing the keypress key to the factory to resolve the correct event as shown in the code below.

interface IEventAction {

}

interface IEventAction<T> : IEvent {
    void Fire(T factor);
    bool CheckCondition(T factor); //check the condition to fire the event
}

class PlanningClose : IEventAction<string> {
    GroupBox _gpb;
    public PlanningClose(GroupBox gpb){
        this._gpb = gpb;
    }

    public void Fire(string factor) {
        this._gpb.SendToBack(); //hide planning groupeBox
    }

    public bool CheckCondition(string factor){
        return factor == "*"; //"*" is keyboard key for close.
    }
}

class frmMain : Form {
    //logic here
    void registerActions() {
        ActionsFactory.Register(new PlanningClose(this._gpbPlanning));
    }
    //logic here
    void frmMain_KeyPress(object sender, KeyPressEventArgs e){
        //during resolve the factory checks if the event is suited be executing 
        //CheckCondition(T factor) and return it if appropriate
        IEventAction evt = ActionsFactory.Resolve<string>(e.keychar);  
        evt.Fire(e.KeyChar);
    }
    //logic here
}

The problem here is that I am managing a lot of key presses in frmMain_KeyPress where I am using the same key several times for different purpose, the problem here is I cant figure out a proper way to handle this problem and keep Action as abstract as possible. I thought about registering named action and resolving them by name also, but I have never used this technique.

//register
ActionsFactory.Register("close_planning", new PlanningClose(this._gpbPlanning);
//call
ActionsFactory.Resolve<string>("close_planning", e.KeyChar);

Does anyone have a better way of implementing this problem. Thank you.
