How to give notecard on touch and still allow grab?

I am very new to scripting, and I'm not too good at it. Can anyone tell me how to modify my script to do the following:

1) Allow ctrl-click and drag to move the object.
2) Right click brings up pie menu, and "touch" gives note card.

alternately...

2) Add a menu item to the pie that says "Info..." that gives out note card.

Right now it just automatically gives the note as soon as I try to grab it. I am unable to move the object without choosing edit.

default
{

    touch_start(integer total_number)
    {
        //  Find out who clicked, and give them a note card
        key giver;
        giver = llDetectedKey(0);  
        string name = llDetectedName(0);
        if (giver != NULL_KEY)
        { 
 
            llGiveInventory(giver, llGetInventoryName(INVENTORY_NOTECARD, 0));
        }
    }

}

Maybe something like this?

touch_start - Reset time
touch_end - get time, and see how long the object was 'touched' for. Use some reasonable limit, say, if it was held for more than 0.5 seconds, it was probably a drag and not someone looking for the notecard. Less than 0.5 seconds, give them the notecard.

Just an idea, I don't know how well it'll work in practice. I've never used touch_end myself. And it may get complicated if multiple people are clicking/dragging the object simultaneously.
