I know I have seen it and I use it.

But I don't know how to search for it in the flows I have.

Problem/scenario:  
`global.DELAY = 3000`  
In the `change` node I want to set a message property to `global.DELAY / 10`.

I remember it is done with the `J:` (expression) option as the qualifier, but......  
blank.

I can't search for that because I don't know if you can search for a `change` node with that setting.

Hey, I'm dumb. I admit it. 😉

that would be

```auto
$globalContext("DELAY") / 10

```
