Made changes to display tooltip window when user navigates through the icons in the toolbar using keyboard arrow keys.

I have already fixed this issue. (Issue:801). I have got LGTM also. But, I have checked in the code when tree was closed. So, all my changes were reverted. So, this new issue is created to upload the same changes.
