if i want to this, i tend to either a) start another win process
as others have said, or b) click New, and in the new window
type "<tail -f foo", Esc (to select that text) and middle click
it to execute it. the only down side of this is that it
doesn't automatically scroll to the bottom when new text arrives,
but that's not always what you want anyway.

it's a powerful technique e.g. a very quick way of getting a date
stamp into the current document: type "<date", Esc, middle click.
