Special Keys

The F5 key allows to save a screenshot as a bmp file in the application directory. These are named cpu.bmp, cache.bmp, mainboard.bmp and memory.bmp.
The F6 key copies the current page in the clipboard.
The F7 key saves the validation cvf file in the current directory.
The F9key switches between CPU clock computation methods
