If you are not using a mouse, you use the tab key to move between fields in a
dialogue box. If you go File/Change dir... and then press tab to move to cursor
from the path text box to the Browse button it appears that the focus moves
correctly, but when you press Enter to activate the browse button the resulting
action is the same as if you had used the mouse and clicked on OK instead.

If you enter some non-existant path in the path box and use the keys to select
the Browse button, you get the error "Unable to set '...' as working directory"

The problem was present in R 2.0.1, I have just upgraded to R 2.2.0 and it still
exists.
