What is the trick to access `global` variables form within a `change` node?

I was wanting to do maths things to it and so to simply set/get it I would then need a `function` node, but someone posted me how to do it.

I seem to remember it was in the `J:` part of the change node.

But I have tried searching the flows and couldn't find it so I tried searching for my question and (alas) also couldn't find it.

Sorry folks.

In a JSONata Expression you can do `$globalContext("FOO")`

Thanks.

I don't think that was how I was shown.

It looked something like:

`J:` for the _type_ of entry in the line. Then something like:  
`{("global.foo")} * 3`

But as I am not sure for what it is I am searching, it makes it difficult to search the flows.

Will a search search in a `change` node for stuff typed?

Found it!

This is how I was shown.

```auto
[{"id":"843af767.23caa8","type":"switch","z":"9b7e7466.a4b698","d":true,"name":"EXTREME HEAT 1","property":"payload","propertyType":"msg","rules":[{"t":"gte","v":"$globalContext(\"Shutdown_temperature\")-10","vt":"jsonata"}],"checkall":"true","repair":false,"outputs":1,"x":1865,"y":340,"wires":[["5da5a554.5275ac"]]}]

```

Ok, the node is disabled. But that is how it was shown to me.

Sorry for not remembering.

Actually you probably are/were right. I just didn't see it as it would be shown in the node.

Thanks again though.
