The mouse capplet in the GNOME Control Center helps to configure properties of the mouse, such as: whether you're left handed or right handed, sensitivity, and mouse speed. The buttons tab controls properties for the mouse buttons. A mouse behaves differently based on whether the user is right or left handed. If they're right handed, the left button is the action button, while the right button is the menu button. The mouse also typically sits on the right hand side of the desk. If the user is left handed, they use the right button as the action button, while the left button is the menu button. It also sits on the left hand of the desk. To configure the hand orientation, select the Left-handed mouse button. If you're right handed, deselect that button. Press Apply to apply your changes. Double-clicking speed can be configured, to let you set how fast you want to double-click. This can be good for disabled people who can't click fast. Select the delay you wish to use on the slider. The more right it is, the longer the delay allowed. You can test the speed by double-clicking on the cake at right. The candle will light on fire if it detected a double-click. Cursors are the part on the desktop that represents where the mouse is. The cursor can be changed for easier use. Gnome's mouse cursors can be configured to look different. For example, if you have a dark desktop, you may want to use the white cursor. To select a theme, simply click the theme you wish to use and click Apply. You will need to logout for this change to occur. Sometimes, you'll lose where the cursor is. If you select the Show position of cursor when the Control key is pressed, the cursor will be animated when you press and release the control key. The mouse cursor can be set to move at different speeds and sensitivities. The following options are available for you to edit: The mouse pointer can move at different speeds across the screen. Everyone has their favorite speed, so the ability to configure this is important. To set your mouse speed, move the bar to either faster or slower in the Mouse speed section. Afterwards, click Apply to test the speed. Once you select your desired speed, click Close. Drag and drop is clicking an object, and dragging it to another place on the screen, causing an event to occur. You need to drag it a certain amount of distance before the system will recognize it as a drag and drop operation. To configure how far to drag it, move the slider left or right.
