The Move tool is so often used in Photoshop and Elements, the software designers gave it top billing in the Tool Panel. Not only that, they also gave it two handy shortcuts.
When you are working with any tool, pressing the letter V on your keyboard replaces the current tool with the Move tool.
If you just want to switch to the Move tool temporarily while working with another tool, press and hold the Ctrl key (Mac: Cmd key.) Now you can click/drag your image into position. When you release the Ctrl key (Mac: Cmd key,) you’ll return to the original tool.
