Enable a screen reader for Windows

1. Download and enable your preferred screen reader. Check the following recommended screen readers:

   • NVDA: use the NVDA 2015 or later. If you are using a 32-bit version of NVDA, you must install 32-bit JRE on your machine, as this version of NVDA requires C:\Windows\SysWOW64\WindowsAccessBridge-32.DLL to work with IntelliJ IDEA. If NVDA cannot locate this file, the NVDA Event Log window displays a message.

   • JAWS: download the version you need and restart your computer to enable the JAWS screen reader.

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. Launch IntelliJ IDEA. The Support screen readers option located in Settings / Preferences | Appearance & Behavior | Appearance will be enabled.

Adjust colors for red-green color vision deficiency

You can adjust colors if you have red-green color vision deficiency. In this case, code fragments such as errors that are usually highlighted in red or strings that are usually green, will change the color (red will change to orange, green will change to blue).
