It took me a long time to find this.
How to change the Long press keys and short press keys to any program you want:

Long pressing RED call button brings us to HTC end key but there are other buttons that you can long press or short press to link it to a program you like such as power button to use slide to unlock (S2U2).

Long_PTT.lnk (push to talk button+long press)
Long_End.lnk (the red key+long press)
Long_Send.lnk (the green key+long press)
Short_PTT.lnk (push to talk button)
Long_Power.lnk (Power button +long press)
Short_Power.lnk (Power button)

If you want to link a program to above buttons then just copy the .exe of that file and paste it as SHORTCUT and then rename it to above and after that put it to \Windows folder !!!! If you want S2U2 when you press power button then just go to file explorer and then to \Program Files\S2U2\s2u2.exe and copy and paste it as short cut and then rename it to Long_Power or Short_power and place it in \Windows folder. press power button and it will start s2u2.
