I am currently working in making the ArcGIS Viewer for Flex V1.3 508 Compliance. As part of the 508 compliance I am trying to assign short cut keys to map controls in the viewer. The viewer has toolbar with zoom in, zoom out,pan controls, and I am trying to assign short cut keys to access these controls. I am following "Accessibility Best Practices for flex" from adobe http://www.adobe.com/accessibility/products/flex/best_practices.html. Does anyone can help me ?
Not sure if it may help you, but map navigation using keyboard is already supported for:
* Pan using the arrow keys (keyboardNavigationEnabled). * Press the + key to zoom in at center of map (keyboardNavigationEnabled). * Press the - key to zoom out at center of map (keyboardNavigationEnabled).
The link shows how it can be done in FlexViewer 2.2 by a configurable widget. Not sure about ArcGIS Viewer for Flex V1.3, but it might give you some ideas.
