If you use the flip tool (2023+), here is a tip that I have not seen documented. If this is obvious, I apologize.
If you forget to hit the copy modifier key (option on mac, probably cntr on windows) before you drag to flip, you can hit the copy modifier key after the flip, and it will become a copy.
So,
select geometry
select flip tool
drag axis (or as Aaron would say axeez) to flip point point and release drag
remember you wanted to actually do a copy-flip
hit the modifier key.

This does not work for me with the standard move or rotate tools.
Maybe it is a Windows versus Mac thing, but if I complete the move or rotation (click to set final position), I can hit the option key all day long and no copy magically appears at the start position. If I am in the middle of the move or rotation, and hit the option key, then copy mode is activated.
No it’s not, they work the same on both. The difference I see now is that flip behaves differently when finishing an operation. The first click does the flip, and it’s done. Not even escape can undo it, unlike move and rotate that require the final click to complete and exit the operation. Interesting.
