In the mid 90’s reservation centers had the operator using a computer with a mouse, while the employees who were blind used keyboard only interfaces. Once the companies realized that the keyboard users were 20 percent more efficient, they cut the mouse from those applications. Of course they left the mouse for solitaire as it is slow dragging cards via a keyboard. Pat Fischer BrailleArt.com – The Art you Touch www.keyboardhelpers.com/timestudy.html Keyboarding
