Press an extra function key or press enter to finish...First you will have to press the extra function key so that the program knows which key you mean. It is important that you do not press any other key than the extra function key. After pressing the key you will be asked to enter the keys name, keycode and default action. This will be discussed in the following paragraphs.
When you entered the information, the program asks again to press an extra function key. If there are no more extra function keys, just press enter to write the output file and terminate the program.
