In a typical text editing application, the cursor can be moved by pressing various keys. These include the four cursor keys, the Page Up and Page Down keys, the Home key, the End key, and various key combinations involving a modifier key such as the Control key.

The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that ...
Synergy is a software application for sharing a keyboard and mouse between multiple computers. It is used in situations where several PCs are used together, with a monitor connected to each, but are to be controlled by one user. The user needs only one keyboard and mouse on the desk — similar to a KVM switch without the video.

Its roots lie in the earliest days of visual editors when line and column navigation was controlled with arrow keys . Today, mouse keys usually refers to the numeric keypad layout ...
Locks-and-keys. Locks-and-keys is a solution to dangling pointers in computer programming languages . The locks-and-keys approach represents pointers as ordered pairs (key, address) where the key is an integer value. Heap-dynamic variables are represented as the storage for the variable plus a cell for an integer lock value.
