Universal access
The Ubuntu desktop includes assistive technologies to support users with various impairments and special needs, and to interact with common assistive devices. Many accessibility features can be accessed from the Universal Access section of System Settings.

- Change text size on the screen — Use larger fonts to make text easier to read.
- Make the keyboard cursor blink — Make the insertion point blink and control how quickly it blinks.
- Quickly locate the pointer — Pressing Ctrl can find your mouse pointer.
