A pointing stick can be used by pushing with the fingers in the general direction the user wants the pointer to move. The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. The relation between pressure and pointer speed can be adjusted, just as mouse speed is adjusted.
As a result, plugging a mouse into a joystick port causes the "joystick" to continuously move in some direction, even if the mouse stays still, whereas plugging a joystick into a mouse port causes the "mouse" to only be able to move a single pixel in each direction.
A comparison of transport proteins [1]. An antiporter (also called exchanger or counter-transporter) is an integral membrane protein that uses secondary active transport to move two or more molecules in opposite directions across a phospholipid membrane.
Mouse keys is a feature that allows controlling a mouse cursor with arrow keys instead. A feature echoed in the Amiga whereby holding the Amiga key would allow a person to move the pointer with the cursor keys in the Workbench (operating system), but most games require a mouse or joystick. The use of arrow keys in games has come back into ...
Strafing in video games is a maneuver which involves moving a controlled character or entity sideways relative to the direction it is facing. This may be done for a variety of reasons, depending on the type of game; for example, in a first-person shooter, strafing would allow one to continue tracking and firing at an opponent while moving in another direction.

A scroll wheel on a conventional mouse may also be used. Moving the wheel in a desired direction moves the content in the same direction. [16] Most mice contain scroll wheels that only scroll up and down, but some mice contain scroll wheels that allow the user to scroll in any direction (up, down, left or right), including diagonal directions.
One may compare linear motion to general motion. In general motion, a particle's position and velocity are described by vectors, which have a magnitude and direction. In linear motion, the directions of all the vectors describing the system are equal and constant which means the objects move along the same axis and do not change direction.
