Template:Pointer

From Grokdoc

A pointer could be several things:

• the mouse cursor,
• the miniature joystick seen on some IBM laptops to control the mouse cursor.

---

A little arrow or hand that, well, points to stuff. Controlled by a pointing device such as a mouse, touch pad, pen or stylus.

A geeky usage of pointer is to mean a variable in a program that holds the address of another variable, such that it "points to" the other variable.
