button

How do I toggle a button to send e.g. value 255 if toggled else value will be 0? Basically on / off for DMX inside the Universe. By using buttons I only get value 1 yet cannot find where to change this? Thanks!

Am I missing something? Where'd the button disappear to? Is there a setting or file that affects that? Referencing to the "Show it now" button in Timeline in the top toolbar next to the Help button top right.

I want to use an on / off button in the universe to mirror Y axis of a given zone. Now, I was able to solve this with two separate button, I turn it on one, I turn it off the other button. How can I turn this on and off with one button?
