When 'playing' a level in 'Content Examples' - what keys do I use??

When I’m in the content examples project, and run a level, what keys do I use to interact with the level?

For example, in the animation level, how do I ‘push a button’, or ‘change a slider’?

This should be really simple…

There is no active game ‘mouse pointer’ in the content example levels…

Movement is accomplished with keys AWDS, jumping is spacebar… direction is mouse… so what are the ‘standard input keys’ for interaction with objects like:

  1. the help question mark
  2. buttons
  3. sliders
