Control-K is a computer command. It is generated by pressing the key while holding down the key on most computer keyboards. Control-K may perform a variety of functions in different systems.
In hypertext environments that use the control key to control the active program, control-K is often used to add, edit, or modify a hyperlink to a Web page. For example, this key combination is used in Windows versions of Microsoft Word and in many browser-based content management systems.
In the Bash shell control-k erases text from the cursor to the end of the current line.
