. The two commits enhanced 'edit' to support text selection through mouse. But the code introduced some bugs resulting the text selection behavior is not very usable and potentially hang in certain platforms. So I'd like to revert them firstly. If there is strong requirement for the text selection through mouse in 'edit' I will refine and re-add the code.
