=== Accessibility ===

Both Flash and HTML text can be read by screen readers. However, special care must be taken to ensure Flash movies are read correctly. For example, if a Flash movie is set to repeat indefinitely, this can cause a screen reader to repeat the content endlessly. Selecting the "Make object accessible" check box in Adobe Flash Professional will create a text-only version of the object for screen readers. It will also hide any motion from the screen reader.<ref>{{cite web|url=https://www.adobe.com/accessibility/products/flash/animation.html|title=Adobe Flash accessibility design guidelines|publisher=Adobe Systems|access-date=May 21, 2011}}</ref> Since Flash content is usually placed on a single webpage, it appears as a single entry in search engine result pages, unless techniques like [[deep linking]] are used with libraries like [[SWFAddress]] to provide multiple links within Flash websites and web applications. [[graphical user interface|User interface widgets]] in Flash objects don't always behave like their host native counterparts. Keyboard, mouse and other accessibility shortcuts may not work unless the webpage developer explicitly adds support for it.
