Windows Magnifier

  • Autore: Cyrille Bougot
  • NVDA compatibility: 2019.2.1 and beyond
  • Download stable version

This add-on improves the use of Windows Magnifier with NVDA.

Funzionalità

  • Allows to report the result of some native Magnifier keyboard commands.
  • Allows to reduce the cases where table navigation commands conflict with Magnifier's commands.
  • Adds some keyboard shortcuts to toggle various native options of the Magnifier.
  • Allow to save and restore the configuration parameters of the Magnifier.
  • Adds some extra features that are not provided by Windows Magnifier (mouse to view, Magnifier window not on top)

Settings

The setting panel of Windows Magnifier add-on allows to configure how NVDA reacts to native Windows Magnifier commands. You may want to have more or less commands reported according to what you are able to see. The panel also contains an option to modify the behaviour of Windows Magnifier control window.

This panel may be opened choosing Preferences -> Settings in the NVDA menu and then selecting the Windows Magnifier category in the Settings window. The keyboard shortcut NVDA+Windows+O then O also allows to open this settings panel directly.

The panel contains the following options:

  • Report view moves: controls what is reported when you move the view with Control+Alt+Arrows commands. The three options are:

    • Off: Nothing is reported.
    • With speech: a speech message indicates the position of the zoomed view on the dimension the view is being moved.
    • With tones: a tone is played and its pitch indicates the position of the zoomed view on the dimension the view is being moved.

    This option does not affect docked view mode.

  • Report screen edges: controls what is reported when you reach the edges of the screen while moving the view with Control+Alt+Arrows commands. The three options are: Off, With speech and With tones. This option does not affect docked view mode.

  • Volume of the tones reporting the position of the view: allows to define the volume of the tones if you have selected to report view moves or screen edges with tones.
  • Report turn on or off: If checked, the Magnifier's state is reported when you use Windows++ or Windows+Escape commands to turn it on or off.
  • Report zoom: If checked, the Magnifier's zoom level is reported when you use Windows++ or Windows+- zoom commands.
  • Report color inversion: If checked, the color inversion state is reported when you use the control+Alt+I toggle command.
  • Report view change: If checked, the view type is reported when you use a command that changes the view type (Control+Alt+M, Control+Alt+F, Control+Alt+D, Control+Alt+L)
  • Report lens or docked window resizing: If checked, a message is reported when you use the resizing commands (Alt+Shift+Arrows). In docked window mode, the height or the width is reported. In lens mode, the new dimension cannot be reported for now. These resizing command do not seem to be available on all versions of Windows; if your Windows version does not support them, you should keep this option unchecked.

  • In documents and list views, pass control+alt+arrows shortcuts to Windows Magnifier: There are three possible choices:

    • Never: The command is not passed to Windows Magnifier and standard NVDA table navigation can operate. When used in documents out of a table, the Control+Alt+Arrow command reports a "Not in a table" error message. This is the standard behaviour of NVDA without this add-on. You can still use NVDA+Windows+O then arrows to move the magnified view.
    • Only when not in table: In table or in list views, Control+Alt+Arrow commands perform standard table navigation. When used in documents out of a table, Control+Alt+Arrow commands perform standard Magnifier view move commands. If you still want to move Windows Magnifier view while in table or in list view, you will need to press NVDA+F2 before using Control+Alt+Arrow commands or alternately use NVDA+Windows+O then arrows. This option is the best compromise if you want to use Control+Alt+Arrow for both Magnifier and table navigation.
    • Always: Control+Alt+Arrow commands moves the Magnifier's view in any case. This option may be useful if you do not use Control+Alt+Arrow to navigate in table, e.g. because you have changed table navigation shortcuts in NVDA or because you exclusively use Easy table navigator add-on for table navigation.

  • Keep Windows Magnifier command window always on top: If unchecked, the Magnifier's control window will not be kept always on top of other windows.

Comandi aggiunti da questo add-on

In addition to native Magnifier commands, this add-on provide additional commands:

Note

  • For computers equipped with an Intel graphic card, control+alt+arrow (left/right/up/down) are also shortcuts to modify the orientation of the screen. These shortcut are enabled by default and conflict with Windows Magnifiers shortcuts to move the view. You will need to disable them to be able to use them for the Magnifier. They can be disabled in the Intel control panel or in the Intel menu present in the system tray.

  • Depending on your Windows version, Alt+Shift+Arrow are Windows Magnifier shortcuts to resize the magnified view (lens or docked). When Magnifier is active (even in full screen mode), these shortcuts are captured by Magnifier and cannot be passed to the application, even if you press NVDA+F2 before. To use these shortcuts in the current application, you need to quit the Magnifier (Windows+Escape) and re-open it after (Windows++). For example in MS word, to decrease title level:

    • Premete Windows+Escape per chiudere l'ingranditore.
    • Premete Alt+Shift+freccia destra per diminuire il livello del titolo selezionato.
    • Premete Windows++ per riaprire l'ingranditore.
