Can a programmable keyboard do this?

[annoyedatKVM]

I need a keyboard to send a
ctrl ctrl 3 enter
or
scrolllock scrolllock 3 enter
signal sequence into a usb kvm with one button press.  I can't use my main keyboard to do this is it is incompatable with the kvm, logitech g15 needs power and doesn't like kvms.

I have read through this forum.  I can't find if sequences such as scroll lock scroll lock can be stored in keyboards.   Can all programmable keyboards handle that?  Any suggestions of the cheapest that would work?  I live in the UK.

Thanks for any help

Have you tried just using a separate key mapping software? You may want to take a look at ATNSoft Key Manager or AutoHotkey, if you haven't already.

The datahand looks too expensive for me I am afraid.  But thanks for the tip it gives me hope

I use autohot key to send my keyboard signals all over the place, I multibox on WoW.  

I can't see how a software solution can do this, the KVM is dumb, it only detects the hard signal at the keyboard designated usb port.
 No use the computer converting the a hard signal at a software level, its too late by then, it's already passed through the kvm.
Unless I could get the computer to pretend it is a keyboard plug it into the input of the KVM and send a signal out over the usb.  But I haven't a clue how to make a computer send a keystroke out through a usb port.  Autohot keys uses the network to pass out the keyboard commands.

As far as I can see I think I need a hardware solution

What about one of the gaming keyboards with onboard memory like the Razer Tarrantula?

get a belkin nostromo.  You can usually find a standard n52 cheap off ebay.  N52te's are the bomb if you can afford them.  But yeah, autohotkey would probably work too.
