i am creating an inventory script that i want the user to press the numbers keys to interact with the bar along the bottom, but i cant get the images to change on key press only when they are clicked. i have tried using the toolbar but i get back errors, if someone knows a way in which to set a the toggle to active that would really help.

thanks in advance

function OnGUI() { var curIndex = 0; GUI.skin = customSkin; GUI.BeginGroup (new Rect (400, 500, 400, 120));

    for(var item : System.Collections.Generic.KeyValuePair.<String, GameObject> in items) {
        //iterate through all the items in the dictionary.
         var rect : Rect = new Rect((width+2) * curIndex, 0, width, buttonHeight);
         var customStyle : GUIStyle;
         var btnToggled : boolean;
         var itemIndex : int;
         itemIndex = curIndex;
         customStyle = "icon_"+item.Key;
         GUI.skin = customSkin;
         btnToggled = GUI.Toggle(rect, btnToggled, curIndex+1+")", customStyle);
         //Create a rect for the button.  It is offset more for each item in the array.
         if(Event.current.Equals (Event.KeyboardEvent (curIndex+1+""))) {
              curItem = item;
              //if the user clicks the button, select it as the current item.
         }
         if (curItem.Key == item.Key){
         btnToggled = true;
         }else{

         }
         curIndex++;
         //increase the offset counter.
    }

    GUI.EndGroup();

}
