Guys as a new user I've been caught out with the history function - in the context of mirroring.
The documentation seems a little light on this area - unless I've missed something. So, a few questions:

1. Exactly which tools are subject to history? Mirror, loft, lathe... any others?

2. How do I know if history is enabled on a selected object?

3. How do I disable it? Step by step please.

4. Can I disable it globally for a function such as mirroring?


Thanks for any enlightenment.
