Thanks Richard. Sorry if I was vague.
Window Fit All displays every object in the scene in the window at the same time, without changing the user’s point of view. It’s faster than maneuvering, and handy if (like me) you’ve lost track of your stuff. I see that Home sometimes does this. I asked about Window Fit All because I’ve seen it in other programs.
3D Cursor Lock would be, for example, checking a Lock checkbox that stopped the 3D Cursor from moving, ever again, until I explicitly uncheck the box. A Hide option would be equally useful.
And I see that sometimes, CTRL-Z works as I expected. I’m finding that the operation of many controls is contextual, and that the contexts are not yet clear to me. I will need practice.

As long as we’re gathered here, let me ask an even stupider question. For me, it would be great to swap Cartesian Coordinates Y and Z, so that Y was height and Z was depth. I wouldn’t be able to do that, would I? My guess is, no, but it is sometimes better to ask than to assume.
Thanks.
