kungsalmanAccording to the user manual (.pdf linked on product page) you can swap the ctrl and caps lock keys using Fn+f7 and it comes with 11 extra keycaps so it might just be that this is an option. I'm hoping to find out what the extra keys are too.
EDIT:
Looks like the extra keys are just the ones with the Fn functions on. Too bad.
DaveerAccording to the product page of the similar keyboard F87 RGB (http://www.ikbc.com.tw/f87) it comes with "8 x Gaming Keys (QWEASD and Arrow Keys)". I assume that those would be included with this keyboard as well, plus 3 additional keys. Two of those might be the switched Caps Lock and Ctrl.
