Live Drawing disconnected shapes?

UPDATE: i just found Monty Martin's guru session, and a tutorial which I think will resolve this. Sorry for spam.
Live Drawing is amazing, but i want to use it to make disconnected shapes, like dots and blobs, not always a continuous line.
I've set a modifier ('option' key) so the trackpad cursor isn't constantly 'on', but when i activate it again it creates a straight line joined from the last point.
I think what i need is for the Live Drawing Actor 'capture' input (see image) to return to a default 'off' position when the cursor/mouse +modifier is inactive.
The simplest thing would be for the Mouse Watcher trigger, which I am using to activate the 'add point' input (see image), to somehow toggle the 'capture' input to 'off' when it is released.
I guess the essence of what I'm after is how to generate a trigger from the absence or removal of a trigger, if that makes sense.
Or how to make an Actor input return to a default state (in this case 'off'), following temporary activation.
You probably all worked this out years ago..:-) I throw myself on the mercy of your scorn...

you can set that input to OFF by triggering a value of zero using a Trigger Value actor. (A value of 1 will turn it ON) you could maybe add this to your option key modifier using a Keyboard Watcher.
That was my first idea too, but the keyboard watcher does not recognize any of the modifier keys.
As a workaround you may define any other key in the keyboard watcher to trigger a zero manually, after finishing one of your drawn forms and then let the trigger out of the mouse watcher turn the live drawing on again.
Just saw your update - successful? It would be interesting to have something that tells 'data flowing' or not.
This may be a solution that works for your. You can play around with the trigger delay to fine tune for your needs.

Thanks so much
...for your different solutions, all of which are expanding my understanding of how to program switches and triggers in Isadora. Using the Trigger Value actor as a binary 'on/off' switch is powerful. Monty talks about this too. In the end I went for a mouse watcher with no modifier triggering a zero/off, so that i can toggle between on and off using the modifier i set for the first Mouse Watcher (img). This is good, but following the tutorial advice, I am now playing with the Stage Mouse Watcher to get something closer to the kind of 'touch = 'on' / release = off' experience.
