Vegas is so much easier than Avid to me. Just click on a video event on the timeline to select it. Put your curser at either edge and drag to shorten, or or put your curser where you wand to split an hit the s key. Just click on an event on the timeline and you can drag it left and right for timing, and up and down to different tracks. The Vegas help file is very good and you can use the search button, (Binoculars) to find answers to specific questions.
Don’t give up on Vegas just yet. If you learned Avid, you can easily learn Vegas.
