'Tools in VisIt Visualization Software?

I am using VisIt to visualize 3D simulation data in the form of VTK files. I am fairly new to this software and was wondering if it has the following three tools:

  1. Measure distance between points in the simulation
  2. Periodically extend data
  3. Anchor or pin an annotation/label to some point in space in the simulation

Do such tools exist in VisIt, specifically if they can be done via mouse clicks as opposed to code (as I do not know the coordinates beforehand)? If so, how/where can they be accessed?
