When I run this function the ansi-term is created but the point
does NOT move to beginning of buffer. Why?
(global-set-key (kbd "M-l") (lambda () (interactive)
(ansi-term "ls")
(beginning-of-buffer)))

That's expected. It's because the output comes from an asynchronous
process and arrives after your function has long given back control to
the command loop. When your (beginning-of-buffer) is evaluated, the
buffer is there but still empty.
That's why such things are typically done in a process sentinel.
Michael.
