Different levels or categories of text or images or both can be selected on a display device with simple commands. A selection region including one of selected text and selected images can be increased or decreased depending upon an executed command. A first command can increase a selection region while a second and different second command can decrease a selection region. Once a maximum amount is selected by using the first command and if the first command is selected again, the selection region can return to the minimum amount of text and images that can be selected. And vice-versa.
