Abstract

In one aspect of the present invention a computer-implemented method is provided of processing input key events associated with user input received from a keyboard-type device, wherein the keyboard-type device selected from at least one of a keyboard and a keypad. In this aspect, input key events associated with a first process active within an operating system are received and monitored for a first predefined input key event associated with user selection of a first key of the keyboard-type device for at least a predetermined time period. In response to identifying the first predefined input key event, the input key events are redirected from the first process to a second process. The input key events are monitored for a second predefined input key event associated with further redirection of the input key events. In response to identifying the second predefined input key event, the input key events are redirected to the first process.
