The two status lights to the left of the Slide Tray will instantly tell you if you have any accessibility problems. A red light means there is an issue that has to be dealt with to ensure the output will meet accessibility guidelines. A yellow light means there is an item that might need to be addressed and requires you to manually check it.
There are some items LecShare cannot check for accessibility standards, like whether or not the correct number of rows or columns in a table are marked as headers. Items colored yellow require the user to check to ensure that the item has the correct settings. If the number of header rows and columns are indicated correctly, click on the "Headers Correct" box to indicate that you have manually checked it.
After you click on a slide in the Slide Tray, the Accessibility Viewer in the upper right corner will show you every element on that slide and whether or not it meets accessibility standards. To edit an item, simply double click on the item. The same color scheme used by the status lights is used here (green = OK, yellow = check, red = error)
