Bind mouse button on F button?

Something like promises program ATNSOFT Key Manager (which I didn't really try, because it is not free, and I didn't want to get hooked on it for thirty days free test).

Also writethat you have free to achieve the desired functionality by installing KeyMan (Keyboard Maniac), and put freeware official key.

To assign any action to a mouse click is an excellent program X-Mouse Button Control. And then you can parse unnecessary five button mouse and solder on Mouse4 or Mouse5 big red button.

it just seems to me that Windows can not distinguish what kind of mouse came the signal button is pressed. therefore, the left and right mouse button to define special actions impossible.
you can use Mouse3 (clicking, scrolling) because it is not the most frequently used button.
\r
complex option would be using the Arduino to simulate a separate HID ratio

joy2mouse and analogues, as well as a lot of software is bundled with the game controllerate allows you to bindit anything and do anything. (well, almost)
\r
every auto-it, autohotkey, nncron and others, allow you to hang a whole series of keystrokes, execute macros, scripts, manipulate Windows, run and kill the processes and change their priority to manage fairvalue, players, browsers, and even space ships by mining ore in the asteroid belts!

Perhaps all will have to do :)

If Windows, you comemorate to do without any programs. habrahabr.ru/blogs/windows/75290/
C the mouse all by analogy.

And I wonder how to remap the keys on the second keyboard to the first was not injured.
