Keyframes

Keyframing is a massive topic. I fear not everything can be covered explicitly, but implicitly by understanding these examples the rest will also makes sense.

• "datapath"
• keyframe object properties (like location, scale, rotation, hide_render)
• keyframe mesh content (move vertices by keyframe)
• keyframe miscellaneous

mention constant interpolation (this avoids the need to place a before and after keyframe)
