Accessibility

Most web browsers allow you to increase or decrease text size by holding down the Ctrl key (Command key on a Macintosh) and pressing the + (plus) key or – (minus) key.

• Ctrl+ = increase text size
• Ctrl- = decrease text size

If these controls do not work for you, try upgrading to the latest version of your browser or visit Web Accessibility Initiative  (W3C) site for additional instructions. To magnify specific parts of your screen, try a tool such as Windows Magnifier.

The volume is often be controlled with a keyboard by pressing the Ctrl key (Command key on a Macintosh) while pressing the F11 or F12 key:

• Ctrl F12 = increase volume
• Ctrl F11 = decrease volume

The mouse pointer is sometimes difficult to see.

The size and color of the mouse-pointer on the screen can be adjusted to make it easier to identify and locate. Most operating systems also provide options to show a trail when the mouse pointer moves around the screen. It also may highlight the mouse pointer when a specific key (such as the Ctrl key) is pressed.

Transcripts

A transcript is the text equivalent of information that is provided in an audio version. This includes both spoken words and non-spoken sounds (such as sound effects).

Captioning

A caption is the process of displaying the transcript for the audio portion of a video presentation that displays as the video is playing. Captions are text that is superimposed over the video and to allow people who are deaf, hard-of-hearing, or that cannot hear the audio (such as those in a crowded room) to be able to visually read the message while the video is playing .

To view captioning on a video

• Click the link to start the video playing
• Click on the Closed Captioning (CC) button to activate the captioning feature

Some videos and webinars use open captions that will automatically appear. However, the Windows Media Player may be required for some online video content. If this media player is already installed on your computer, the player will come up automatically. If not, you can be downloaded it here: Microsoft Media Player download.
