Is there a facility in Vegas where I can select all -- but only from where my cursor is? That would be a great facility and save me a tremendous amount of time, rather than selecting every event.
That works great on a single track (and I DO use it all the time). However, that will NOT work if you want to do it for ALL tracks. That's where scripting comes in handy. Scripts like this one will do the same for ALL tracks.
A very simple way is to use "Auto Ripple" 3rd option "All track markers and regions" Assign that to a hotkey (mine is F12). If activated you can then click on any clip on any track and drag left or right and it'll move all the media with it.
This is very useful if you have multiple layered effects after the cursor position and don't want to mess with it.
