# &app; Manual V&manrevision;

## Introduction

The &app; application enables you to view image files. &app; provides the following features:

&app; is a dynamic onscreen keyboard for UNIX and UNIX-like operating systems. It features Direct Selection, Dwell Selection, Automatic Scanning and Inverse Scanning access methods and includes word completion.

GOK includes an alphanumeric keyboard and a keyboard for launching applications. Keyboards are specified in XML enabling existing keyboards to be modified and new keyboards to be created. The access methods are also specified in XML providing the ability to modify existing access methods and create new ones.

GOK is not limited to presenting keyboards that have been designed by hand and is able to dynamically create keyboards so that it can adapt to the user's current situation. GOK is able to redisplay components of the user interfaces of running applications directly within GOK as keyboards. This provides efficient access to elements of the user interface, removing the need to navigate the interface indirectly though keyboard accelerators. GOK supports the redisplay of application menus and toolbars. GOK contains a window activator keyboard that lists the current windows on the desktop and provides the ability to switch between them.

Users have the option of setting key width, height, and spacing as well as visual and auditory feedback on highlighting and selection.

GOK is constantly evolving.
