Positioning symbols using grid snap
You can use grid snap to automatically position symbols within the squares of the grid. When grid snap is on, the symbols snap to the grid when you move them. Grid snap does not affect links, notes or draw objects.
•On the View menu, choose Grid Settings, then select the Snap to Grid box.
Grid snap is on when a tick appears in the Snap to Grid box.
Tip: To temporarily suspend grid snap, press the Control and Shift keys while dragging a symbol, then release the Control and Shift keys when the symbol is where you want it.
