47 :: What is Mouse Cursor?

The mouse cursor is a little picture that represents the location on the screen you want to select. You can move the mouse cursor by moving the mouse device. Once the mouse cursor is over the item to want to interact with, you can click or double-click to activate that item. In many cases, the picture you see for the mouse cursor will change, depending on what is underneath it. For example, if you move the mouse cursor over this link, the mouse cursor will probably change into a pointing hand (depending on your software). This indicates that you can single-click to go to that link.
Please note that there is a separate text cursor that shows where text will appear as you type. You can not just move the mouse cursor to where you want text and start typing; you must first click to move the text cursor to that location.
