Cannot Get Resources to Launch with Keyboard Input -- 508 Help Please! Jan 09, 2015 By Richard Blunt Hello Heroes, I'm working a course that must be 508 compliant. I can navigate around the player to get to the resources tab by tabbing to it with my keyboard. I hit the Enter key to activate the Resource pull-down menu. I can use the up and down arrow keys to select the resource (web link of attached document). If I hit the Enter key again, nothing happens. How do I select the highlighted resource to "activate" it using only my keyboard?
