@kjstepanekFor triggering videos with the arrow button you have to use the "keyboard watcher" actor. Assign the arrow key to the right to add 1 to the float counter and the arrow key to the left to subtract 1 to the float counter. This way you can cycle through your videos. To assign the arrow keys to the "keyboard watcher" actor click into the black field of the "key range" input. Type a single quotation mark (') on the keyboard, then click on the right arrow and again a single quotation mark ('). Do the same on a second Keyboard watcher for the left arrow. You will see an empty space between the quotation marks, but thats fine.Best Michel
