Nudge an Object in PowerPoint
When you nudge an object in PowerPoint, the object moves in small increments. The direction the object moves depends on which arrow key you press. Select the object then use the arrow keys on your keyboard to move the object left, right, up, or down until it’s positioned exactly where you want it. If the default PowerPoint setting for nudging is too large for a specific need, manually adjust the increments of movement. Press and hold Ctrl while pressing the arrow keys to move in 1.25-point increments.
Reduce Default Nudge Setting
When you first install PowerPoint, the Snap Object to Grid feature is turned on. This setting determines the distance for the nudge as well. The default nudge setting is six points when Snap Objects to Grid is turned on. If you turn off Snap Objects to Grid, the nudge default setting is 1.25 points. To turn Snap Objects to Grid off:
Objects and Arrows
In addition to using Ctrl to modify an arrow press to decrease the nudge size, press the Alt key with the left and right arrows to rotate the object left or right. Press Shift plus either the down or left arrow to make the object smaller, or Shift plus the right or up arrow to make it bigger. Similarly, using Ctrl+Shift makes the size of the increase or decrease smaller to permit more granular keyboard edits.
