automatic scrolling a field to the bottom when Text is entered

[Sarah]

How about trapping the keyUp message (if you want to scroll as the user 
types) or closeField / exitField if you just want to scroll when they 
have finished. Note: if they are typing into the field you want 
scrolled, it will scroll automatically when needed, indeed if they are 
typing in the middle and you scroll to the end, they might get a bit 
upset :-)

The actual script I use for scrolling is:

set the vScroll of field "My Field" to the number of lines in field "My 
Field" \
	* the effective textHeight of field "My Field"

You have to use "effective" because the text size may only be inherited 
and may not have been set.

Cheers,
Sarah
