Hi, How can we activate the MK 500 keys? I have 3 buttons on a Web page  Start, Cancel , End On pressing the left key I want to trigger the Start and the middle button must trigger the Cancel and right button must trigger the End, Should we modify the mkconfig.reg of MK500? if so what values we need to set ?   In MK1100 we used to set the following values in mkconfig.reg and it worked fine. [HKEY_LOCAL_MACHINE\Software\Symbol\ButtonsDriver] "Button_1"=dword:71 "Button_2"=dword:72 "Button_4"=dword:25 Do we need to do the same for MK 500's mkconfig,reg file? Thanks in advance. Santosh
