## Enabling Accessibility
## Manually enabling accessibility features
Electron applications keep accessibility disabled by default for performance
reasons but there are multiple ways to enable it.
Electron applications will automatically enable accessibility features in the
presence of assistive technology (e.g. [JAWS](https://www.freedomscientific.com/products/software/jaws/)
on Windows or [VoiceOver](https://help.apple.com/voiceover/mac/10.15/) on macOS).
See Chrome's [accessibility documentation][a11y-docs] for more details.
### Inside Application
You can also manually toggle these features either within your Electron application
or by setting flags in third-party native software.
By using [`app.setAccessibilitySupportEnabled(enabled)`][setAccessibilitySupportEnabled],
you can expose accessibility switch to users in the application preferences.
User's system assistive utilities have priority over this setting and will
override it.
### Using Electron's API
### Assistive Technology
By using the [`app.setAccessibilitySupportEnabled(enabled)`][setAccessibilitySupportEnabled]
API, you can manually expose Chrome's accessibility tree to users in the application preferences.
Note that the user's system assistive utilities have priority over this setting and
will override it.
Electron application will enable accessibility automatically when it detects
assistive technology (Windows) or VoiceOver (macOS). See Chrome's
[accessibility documentation][a11y-docs] for more details.
### Within third-party software
On macOS, third-party assistive technology can switch accessibility inside
Electron applications by setting the attribute `AXManualAccessibility`
