Configuring with my own keyboard

[oz123]

I want to configure this program to work when I press Win_L.

Using xev I found:

KeyRelease event, serial 38, synthetic NO, window 0xc00001,
    root 0x79c, subw 0x0, time 14661661, (-529,393), root:(342,858),
    state 0x40, keycode 133 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

I did the following patch:

                         break;
                     case 17: /* W */

However, pressing and holding the Win_L together with E or any other key down not move the mouse pointer. What am I missing here?

Also, here are my input devices:

$ ls /dev/input/by-id/

and how i run the programm:

sudo ./keyboard_mouse /dev/input/by-id/usb-0911_2188-event-if01
