Usually the `inject` node injects stuff in `msg.payload`.
You can edit the `topic` in another field.
Just because I want to optimise node usage:
Is there a way to make the `inject` node send a `msg.flush` message?
I'm guessing it uses the `{ }` option.
In a `function` node, it is this:
```auto
msg = {
'flush':'blah'
};
```
But I am not getting how to put that in the `inject` node.
Please.

No. The Inject node can only set payload and/or topic.

On that, it is the `delay` node which has caught my interest.
It says if I inject a `flush` all messages will be flushed.
To me that means they are forgotten.
(Nic, I saw your reply come in. I'll read it after posting this)
This flow is basically what I want done.
I press the `message` node. It is delayed 5 seconds.
But as I see it, if I press the `flush` button the node should be flushed.
I still get the message.
Why?
Ah! I need to send a `reset` message too.
My bad.
Post left to help anyone else who may fall for that trap.

No
Reset will reset the node. I.E. forget everything (which is what you want.)
Flush will send everything stored up immediately (like unblocking/flushing a pipe)

My bad.
I tripped on that. I read it and mis-parsed it.
~~What I think it was is I am using some `trigger` and some `delay` nodes.~~~~ In the `trigger` node `reset` clears all messages. In the `delay` node `reset` . . . . I'm confused. I'll shut up.~~
All working now.
Thanks.
