On PC, you can hold down Ctrl and use the arrow keys to move one pixel at a time. Is there a way to do the same thing on Mac? I can't figure it out.

Hi Pope,
Edit: fixed as of 2017/05/23.  Use Cmd+Arrows.

It doesn't appear that there is a key for moving one pixel at a time on a Mac.  I've logged it as a ticket, and will post back here when it rolls out.

In the meantime, you can use the Properties panel to enter a precise location, or go up to Edit > Snap Objects to Grid and turn that off.

Hi Pope,
The release on May 23rd should have fixed this issue.  Please update SmartBuilder, and try it out!  It should be Cmd+Arrows.
