After you have tested your program you can run one of the supported programmers. You can also press F4 or click on the 
button.
Some programmers support the auto flash option from the programmers options.
When you select this option, the programmer window will not be visible, but the chip will be erased, programmed and verified automatically. The progress will be visible in the IDE-menu bar.
Different serial comport and parallel printer port based programmers are supported. You must select one first with the Options Programmers menu.
