There was an addon where when you press crtl space it would bring up a menu for the manipulator. I found an addon for it called Manipulator Menu which you could hit crtl space and you could select from a pop up widget to use rotate location scale manipulator instead of having to click down on the bottom and I believe even if you just keep hiting crtl space it will cycle throw the 3 different transform rotate and scale. I had a virus alil while about had to delete everything of my PC and now I can not find this anywhere in the addons or even a working link.
I didn't find the right solution from the Internet.
