Moving objects around your PowerPoint slides in tiny, tiny little jumps instead of larger moves, simply by holding down the Ctrl key.
The simple way to position an image or object in a PowerPoint slide is either dragging with the mouse or using the arrow keys – obviously. Either option is usually enough but the moves jump in relatively large gaps.
If you want objects to move in finer, smaller increments that’s called a nudge.
Hold down the Ctrl button (the mouse pointer changes) then use the arrow keys.
That’s alĺ there is to it. Beware, don’t hold Ctrl then move the object with the mouse — that will make a copy of the object, no nudging!
