(not wanting to babble on)

Ok, reading that link and sub-link to [Button icons example](https://discourse.nodered.org/t/examples-of-colour-change-button-and-switch/3650) I already am . . . confused with the flow.

In the `function` node:  
`var state = context.state || false;`

I went through a horrible learning curve with context stuff.

I thought it should be:  
`var state = context.get("state") || false;`

I shall have to let that slip as a _slicker way_ to do it.  
But just saying when I see things like that, it makes a smooth journey less smooth.
