How does a scrollbar get a name?

[graham samuel]

I'm sure this is a dumb question, but in the RR docs one sees  
references to scrollbars, as in this example from the article on the  
scrollbar object:

> set the style of scrollbar "Progress" to progress
> if the thumbPosition of scrollbar "Level" > 400 then doOverflow
>
This indicates that scrollbars have names: now, if I have a common or  
garden scrolling field, say "myField", with an active scrollbar  
(let's say a vertical one), what is its name? It doesn't seem to be  
"myField", and I don't know how to refer to it or even see it in the  
Object Inspector in the IDE. I ask because I want to do things like  
scroll down to the end by scripting (which curiously enough I've  
never done before) and it seems that the first step is addressing the  
scrollbar.

Any advice gratefully received.

Even more dumbly, maybe someone can point me at a document which  
explains how to make sure the last line of a scrolling field is  
always visible (i.e. the thumb position is always at the bottom of  
the scrollbar). I have a horrible feeling everyone knows this except me.
