Deliberately bypassing the filter will not endear you to the Massassi staff. Remember that you agreed to the forum rules when you registered to post here. Also, don't leave any of those "acronyms" in your patch.
Anyways, I found your problem. The order of bins in the items.dat is important for hotkeys. Each bin in the items.dat with a flag of 0x100 will be given a hotkey. In the jkstrings.uni, each hotkey is assigned a string of text explaining what it's for. The way JK determines which string is for which hotkey is by the order in which they are listed.
You had your new hotkey right after the weapon bins in the items.dat, but you had the description in the jkstrings at the end of the list. That threw your hotkeys out of line, and so it didn't work. To fix this, put your hotkey bin just before the hotkeyOffset line near the end of the items.dat.
That will fix the problem.
