I am having a bit of confusion on these menu items, and especially the tool bar buttons.
If I select an object and say flip vertically, would that mean bottom becomes top and top becomes bottom? However, the action done is flipping about the vertical: left becomes right and right becomes left.
The Tool Bar buttons are the same. They point up and down as if it will flip top/bottom but it does left/right.
I can get the behavior eventually but I have to remember what it really does.
