Sometimes absolute precision is not required. You've placed some element and want to move it around but don't want to type in distances to do this. You just want to play. Enter Nudge.
Nudge is a tool that has no ribbon icon yet can be invoked using the arrow keys anytime you have an element in selection.
Select an element and press left, right, up, or down. The element will move a set number of units with each key press. This works in most views.
The distance of each nudge is derived from your zoom scale.
If the element is not moving fast enough zoom out. If it's moving too fast zoom in.
If you are zoomed in yet want to move more quickly hold Shift + Arrow Key. This will increase the nudge distance by a factor ~10X (in my testing). I'm told this behavior is called Super Nudge.
