Using HTML Input Field in a Grid

As the topic says, I've been using an HTML imput field in a grid.
I noticed that using the mouse to select the contents of the input field does not work, nor does SHIFT+HOME.
I assume that the grid is capturing these keystrokes before the input field gets them.
Is there any easy way to override this behavior?
Thanks in advance,
Alan

Never mind, found the answer:
obj.setEvent("onselectstart", "");
