Hello

I'm trying to understand the state mechanism. I'm beginning to get a clue 
so I thought I'd write it down before I forgot.

In the "tabs" example there is the following code:

```
<<tabs "SampleTabOne SampleTabTwo SampleTabThree SampleTabFour" 
"SampleTabOne" "$:/state/tab1">>
```

I made a tiddler called StateWatcher with the following code

```
<$list filter="[prefix[$:/state/tab1]]">
Content of <<currentTiddler>> =
<$transclude tiddler = <<currentTiddler>>
/>
</$list>

```

The first time I load the tiddler
containing the tabs the StateWatcher shows nothing. When I click on a tab 
the stateWatcher says there is a tiddler called

`$:/state/tab1-2537135` and this 
tiddler contains the name of the tab I just clicked on.

If I close the window containing the tabs the state tiddler is not 
destroyed. But it's not written to disk - so the state change is transient.

This thing with a name like ($:/state/tab1-2889173) seems to be what the 
documentation calls a `state tiddler` I'd have called it a `Global Variable 
whose value is wiki text`

I'm not sure how to create a state tiddler - so some more experimentation 
is in order.

Cheers

/Joe
