Isis707 To add to Spinebot's answer, in Spine, the arrow keys function differently depending on the tool currently selected. When the Rotate tool is selected, the arrow keys rotate the selected item, and when the Translate tool is selected, the arrow keys move the selected item.
In Spine, holding down the Shift key allows for precise adjustments. When the Translate tool is selected, pressing the arrow keys and Shift key simultaneously moves the selected item by one pixel at a time. You can also transform the selected item by clicking and dragging the numeric box, but holding down the Shift key while doing so reduces the amount of change.
These various methods are explained in the Transform tools section of the Spine User Guide:
