Navigate PowerPoint videos with bookmarks

Those who want to show a number of scenes from a video in their PowerPoint 2010 presentation can do so easier by placing bookmarks. The next sequence appears with a click, making things much easier. To insert bookmarks, users first click on the video and select the menu Video Tools/Playback.
Then they look for the desired scene and click on Add Bookmark.
The marking appears as a yellow spot on the play list. To control, they click with the mouse or use the key combination Alt+End to go to the next bookmark and Alt+Home to go to previous bookmark.
