I don’t think it is a natural font that comes with Work, etc but…. download it and save it to your desktop. Then go to Control panel and change the VIEW ( top right ) from Category to Large icons. You will then see the FONTS folder ICON. Double click it to open the folder and you will see all the other fonts you have. Then… just drag and drop the Autumn font into the folder and it will ask you if you want to install it. Just say yes and it is done. Hope you have success…Then open Vegas and it will be in your list of available fonts,,,,
In the PAN and CROP tool section you will see a small icon with a line with arrow head on both end. If you click it, it will change to All movements or only Up or only Sideways
