[news.eclipse.platform.swt] are sashforms keyboard accessible? (resize)

[amywu@xxxxxxxxxxxxxxxxxxxxxxxxxxx (Amy W.)]

Hi,
  I was wondering if there is any way to resize the objects in a SashForm
using the keyboard.  For example, I have a SashForm that contains a
TableViewer on the left panel, and an editor on the right panel.  Users
can resize to make the TableViewer wider/editor thinner or vice versa
using the mouse, but how can they perform the same operation using the
keyboard?

Thanks in advance,
amy
