Accessibility features

1. Download and enable your preferred screen reader:

   Windows

   macOS

   • NVDA: use the NVDA 2019.3 or later version for compatibility with 64-bit Java applications, such as DataSpell.

     Download, install, and enable NVDA.

   • JAWS: use the JAWS 12.0.1158 64-bit or later version for compatibility with 64-bit Java applications, such as DataSpell.

     Download the version you need and restart your computer to enable the JAWS screen reader.

   VoiceOver

2. Ensure you have installed Java Access Bridge and the proper Java version for your screen reader, as follows:

   • To enable Java Access Bridge, open the command prompt and type [JRE_HOME]\bin\jabswitch -enable, where [JRE_HOME] is the directory of the JRE on your machine. For Java version 1.8, Java Access Bridge is part of JDK and you don't need to download it separately. Use control panel to enable the Java Access Bridge.

   • If your screen reader is 32-bit, install the 32-bit JRE version 1.7 or later. If your screen reader is 64-bit, install the 64-bit JRE version 1.7 or later.

   Your computer may have multiple versions of some important components of Java Access Bridge and they may not be compatible across versions. You need to verify that your Java Access Bridge configuration is correct.

   If your screen reader is 32-bit, ensure that C:\Windows\SysWOW64\WindowsAccessBridge-32.DLL is present and has a version number of 7.x.x.x or later. The file's description should read "Java(TM) Platform SE 7".

3. DataSpell automatically shows a prompt suggesting to enable the screen reader support if its installation was detected.

   In the dialog that opens, click Enable when you first launch DataSpell.

   The screen reader support can also be activated later or manually for already installed and configured versions of DataSpell.

1. Download and install DataSpell.

   note

   For Windows and macOS, when DataSpell detects a screen reader on the first launch, it displays a dialog where you can enable a screen reader for DataSpell.

2. To enable screen reader support before the initial launch of DataSpell, do the following:

   1. Open the configuration directory that contains personal settings, such as, keymaps, color schemes, and so on.

      Windows

      macOS

      Syntax

      %APPDATA%\JetBrains\<product><version>

      Example

      C:\Users\JohnS\AppData\Roaming\JetBrains\DataSpell2023.1

      Syntax

      ~/Library/Application Support/JetBrains/<product><version>

      Example

      ~/Library/Application Support/JetBrains/DataSpell2023.1

   2. Create a file called idea.properties.

   3. Add the ide.support.screenreaders.enabled=true property to the file you have created.

3. Launch DataSpell. The Support screen readers option located in Settings | Appearance & Behavior | Appearance will be enabled.

   note

   When the Support screen readers option is enabled, DataSpell disables tooltips for icons in the main toolbar, switches controls to a keyboard, and adapts some controls for screen readers.

You can adjust IDE and editor colors if you have red-green color vision deficiency.
