Moving a flag symbol
1 Select the flag symbol by placing the cursor inside the symbol and clicking the left mouse button.
2 Place the cursor within the selected flag symbol.
3 Drag the flag symbol by pressing the left mouse button and holding it down until a temporary dotted rectangle appears and the cursor changes to a hand.
4 Move the flag symbol into its new location and release the left mouse button.
All logical connections with flag symbols will remain connected; therefore, if the logical position of the flag symbol has been changed, then the flag symbol will be logically reconnected in addition to being moved.
