Hello to you all,

I was not aware that this been filed as a bug! The matter of fact, myself and many others thought of it as an advantage of gedit over other editors and we do use it intensively.
Now, we do seriously miss it after upgrading to ubuntu 16.04 which comes shipped with the latest gedit version.

But, since there are different preferences here as you may find, perhaps an option under preferences would be great where one can enjoy gedit treating underscore as word delimiter or the other way.

Thank you,
