This manual describes version &appversion; of &appname;.

## Introduction

The &app; application enables users with limited vision, or no vision, to use the GNOME Desktop and associated applications. &app; provides the following functionality:

Screen reader

  The screen reader enables non-visual access to standard applications in the desktop, using speech and Braille output.

Magnifier

  The magnifier provides automated focus tracking and fullscreen magnification to aid low-vision users.

## Getting Started

### To Start Gnopernicus

You can start &app; in the following ways:

Menu

  Choose Applications Accessibility Screen Reader and Magnifier .

Command line

  Execute the following command: `gnopernicus`

  You can use the `-d` option to specify default settings.

### When You Start Gnopernicus

When you start &app;, the Gnopernicus menu window appears:

#### &app; Menu Window

Shows Gnopernicus menu window. Contains launchers for Startup Mode, Preferences, Default Preferences, Minimize, Help, About, and Quit.

The Gnopernicus menu window contains the following items:

Startup Mode

  The Startup Mode dialog enables you to choose the functionality that you want &app; to provide when you launch the application. You can use the dialog to apply functionality changes while you are using the application.

Preferences

  Click on this item to adjust the settings for speech output, magnifier behavior, Braille output, Braille monitor, mouse behavior, and key mapping.

Default Preferences

  Click on this item at any time to load the default settings for &app;.

Minimize

  Click on this item to minimize the Gnopernicus menu window.

Help

  Click on this item to open the Help manual for &app;.

About

  Click on this item to read developer information about the &app; application.

Quit

  Click on this item to exit &app; at any time.

## Usage

### To Activate Speech Output

Speech output is normally active by default when &app; starts. However, if there is no speech output, click on Startup Mode in the &app; menu window, then select the Speech option in the Startup Mode dialog.

Some useful assigned actions on the numeric keypad that you can use to work with the Speech output feature are as follows:

Numeric Keypad Code | Assigned Action
--- | ---
L08K13 | Pause or continue reading a large chunk of text.
L08K01 | Decrease the speech volume.
L00K05 | Repeat the last utterance. To spell out characters, press Ctrl Left Arrow.
L03K04 | Provide speech output of the complete contents of a window through the hierarchy of the contents. This is called a logical review.
L03K05 | Provide speech output of the complete contents of a window flattening the hierarchy in a left-to-right top-to-bottom way. This is called a spatial review.

For information about how to use different keypad layers, see .

### To Activate Braille Output

Click on Startup Mode in the &app; menu window, then select the Braille option in the Startup Mode dialog. The application translates all system output to Braille for display on a Braille device.

### To Start the Magnifier

Click on Startup Mode in the &app; menu window, then select the Magnifier option in the Startup Mode dialog.

When the magnifier is activated, half of the screen appears normal size and the other half of the screen is magnified. The location of the cursor on the normal-size screen is indicated by a mobile cross-hair on the magnified part of the screen.

### To Start the Braille Monitor

You can start Braille Monitor in the following ways:

&app; menu window

  Click on Startup Mode, then select the Braille Monitor option.

Command line

  Execute the following command: `/usr/libexec/brlmonitor`

  You can specify the following options with the `brlmonitor` command:

  [-column | -c] | Number of columns on the display
  [-line | -l] | Number of lines on the display
  [-mode | -m] | Specifies the font: [normal]
  [-port | -p] | UDP port number

The purpose of the Braille Monitor is to show you the output that is sent to a Braille device. You can view the output in standard text format, Braille format, or both formats in the Braille Monitor.

### To Start Gnopernicus in Minimized Mode

You can start &app; with the main window minimized, but you can still use the &app; functions. To do this, click on Startup Mode in the &app; menu window, then select the Start minimized option.

### Command Mapping With Layer Keys

&app; functions are mapped onto keys on the numeric keypad. Because the number of keys on the numeric keypad is limited, the functions are assigned in layers. Any key can have multiple functions, depending on which layer is active. You can use the assigned layers of the &app; numeric keypad to work with the different functional areas of the application. The numeric keypad codes are written as follows:

LayernnKeynn

Explanation:

Layernn | Represents the number of the keypad layer.
Keynn | Represents the key value.

#### To Switch Between Numeric Keypad Layers

To switch between numeric keypad layers, perform the following actions:

1. Press the Num Lock key to switch on Num Lock.

2. Press the 0 key on the numeric keypad.

3. Press the key on the numeric keypad that corresponds to the layer you want to activate. See for more information about which keys are assigned to each layer. You must perform this action within five seconds of the first action. If you do not press the layer number within five seconds, then &app; does not change the current layer.

#### To Modify Defined Layer Keys

To modify layer keys that are already defined, perform the following steps:

1. Click on Command Mapping in the &app; Preferences menu window.

2. Open the Layers tab in the Command Mapping dialog.

3. Select the layer code you want to modify.

4. Click Modify.

5. Make your modifications.

6. Click OK.

#### To Define Your Own Keyboard Shortcuts

To assign your own keyboard shortcuts for commands, perform the following steps:

1. Click on Command Mapping in the &app; Preferences menu window.

2. Open the User defined tab in the Command Mapping dialog.

3. Click Add. The Add User Defined Key dialog is displayed.

4. Select the modifier key that you want to use from the Modifier keys options.

5. Select the key that you want to use from the Key drop-down list.

6. Click OK. The Commands List dialog is displayed.

7. Select the command that you want to associate with the new layer key from the Commands list.

8. Click OK.

#### Default Gnopernicus Command Mapping

Currently, &app; functions are mapped on to 11 layers, from 00 to 10. It is possible to use up to 16 layers.

The layer numbers and corresponding numeric keypad keys are as follows:
