when a control is not a control

OK we use this to take control:

llTakeControls(CONTROL_FWD | CONTROL_BACK | CONTROL_RIGHT | CONTROL_LEFT | CONTROL_ROT_RIGHT | CONTROL_ROT_LEFT, TRUE, FALSE);

To capture the controls with usesomething like this for the various combinations and apply an associated event etc.:

if(level & (CONTROL_RIGHT|CONTROL_ROT_RIGHT))

Now is there anyway to clock when NO controlls are being changed or held?

You will get something in edge but a zero level when everything has been released. You could stash that away in a variable and use it in a timer or whatever, if you need some kind of "idle" action. You'll probably want to set that variable to nothing held on attach etc., until a control event tells you otherwise.

you can test for key pressed, held and released:

control(key id, integer down, integer new)
   {
       integer pressed = down & new;
       integer held = down & ~new;
       integer released = ~down & new;
...

so you can detect when all keys are released! what more can you ask?
You can not test for no keys held, because that will not trigger an event.
