I am not understanding how to use it.

Alas looking in the `import/examples` there aren't any.

Could someone _show_ me how to use it?

I'm missing something.

All I can manage is `link - in` --\> `link - call` --\> `link - out`

But I don't know what to do from there.  
Yes, I know this is one side of things. But the other _side_ would be the normal flow which is calling this.

Thanks in advance.

I'm not near my laptop so I can't share an example flow for you, but I can try to explain it.

First up, here is how it was described in the release blog post:

> The new Link Call node can be used alongside the Link-In/Out nodes to create subroutine-like flows.

> If you have a flow that starts with a Link-In node and ends with a Link-Out node that has been put into its new ‘return’ mode (giving the node a different icon), the Link Call node can be used to pass that flow a message and the result is passed back to the calling node.

> As an alternative to using subflows, this is great for creating little utility flows that you want to reuse in multiple places.

Hopefully the image helps give you a sense of what that all means.

If that doesn't help, I'll share an example flow in the morning.

Right! I was doing it back to front!

Thanks!

(Sorry, I know I said it before but I have the latest version and there is the tour. Somehow I have messed up the colours on the browser. Did that one day when logging in to the edit screen and the contrast between the text and background is poor so I can't read it. Don't know how to edit the colour as I had never been asked to "set it" before. Just happened a few weeks ago when I was logging in.)

If you are using a custom theme then make sure you are using the latest version of it.

No I think this is FireFox....

I got the "enter password" requester when I was logging into an edit screen.  
I accidentally clicked on something and was looking at a colour requester. (Keh!!??)  
(This is while the password requester is/was visible. So to me that is the browser end of things.)

I clicked a nominal colour and now it is set.

&\*&^#@! if I know how to get to change it and maybe fix the contrast problem it is causing.
