Zoom Tools is a set of simple scripts enabling the user to quickly zoom in and zoom out of the timeline without use of the mouse wheel. Scripts include ZoomToProject which zooms out to the length of the entire project; ZoomToLoop which zooms into the selection loop; ZoomToEvents which zooms into selected events and finally, ZoomToCursor which zooms in at the cursor position. The amount of “zoom in” is controlled by a GUI which enables the user to set the timeline range displayed using either Time or Frames.
