Line 1: [[Image:Macintosh Classic II Left Side Reset Interrupt Switch.jpg\|thumb\|250px\|The interrupt button/programmer's key protruding from the air vent on the left hand side of an Apple [[~~Macintosh Classic II\|~~Macintosh Classic II]] computer (left with a circle symbol)]] The '''Programmer's Key''', or ''interrupt button'', is a button or switch on a [[computer]] which causes an [[asynchronous]] [[interrupt]] request (IRQ) to be sent to the [[central processing unit\|processor]]. If a [[debugger]] is installed on the machine, it is activated when the interrupt request is processed, allowing the user to view and usually modify the computer's internal memory. This is quite useful in [[debugging]] software, which is why it gets its name.
