Abstract

An assistance method and system. The method includes retrieving by a computer processor of a computing system comprising a touch screen display, an enable command for enabling a keyboard configuration menu for a virtual touch screen keyboard presented by the touch screen of said computing system. The computer processor presents the keyboard configuration menu to the user. The computer processor receives a modify command for modifying specified configuration settings associated with each key of the virtual touch screen keyboard. The computer processor generates and saves modified configuration settings associated with said specified configuration settings. The computer processor disables the keyboard configuration menu.
