What happened to Draw nudge?

I used to use + to nudge an object, but that does something else entirely now, I don’t even know what.
Also, I still can’t get the selection arrow to be an arrow. It’s always the glove when hovering over an object, which makes it really hard to know which object I’m selecting without zooming way in. Like selecting a line on a square can be maddening - zooming into a line as far as you want and it’s still dimensionless.

Took me a long time to figure out why the nudge sometimes suddenly stops working. If this is happening to you, click the Apple logo in the top left corner, select System Preferences > Keyboard > Input Sources > U.S. (If U.S. isn’t in the list, click the “+” button and find it via the dialog boxes). Other options may work too, but something that DOESNT work is “Unicode Hex Input”. Everything else seems normal, but the nudge stops working for this input source.
