my first and biggest pet peeve be the auto-numlock feature which the keyboard default to every time the pc be restart . my computer require every user to sign in when the pc be restart , re-awaken from sleep mode or when it be interrupt from screen-saver mode . when I first restart the pc , I could not sign in . after multiple attempt , I have to use the old keyboard to sign in . once sign in , I open up Notepad and type in my password with this keyboard - that be when I discover the middle set of key be default to the num-lock feature . it be a pain in the arse to have to unlock the numlock everytime the pc be restart . the instruction manual do not indicate a way to turn off the num-lock feature , but do indicate that the keyboard default to numlock and to use the fn and numblock key to turn it off . horrible design . my second pet peeve be the lack of dedicate media key . my old ioGear keyboard have dedicate media key for Windows Media Player or any other playback software . I use this a lot , because I be often listen to my mp3 playlist while surf the web or work on the pc . have to use the fn key again with the function key in the top row require two hand to play media , instead of one hand with my old ioGear keyboard . my third pet peeve be the location of the touchpad . have own 6 laptop in the past 9 year , 3 laptop currently , navigation on the touchpad often require 2 hand - one hand for move the cursor and the other hand control the button -lrb- s -rrb- . this be fairly easy on a laptop , because the touch pad be centered and at the bottom of the laptop , under the keyboard . on this keyboard , it be on the right , upper corner , where it be almost impossible to use two hand . plan on become extremely dextrous with you right finger and if you be left-handed , then good luck . I be still give this 3 star . because it be a full-size keyboard . I will keep and use this keyboard when I be do extensive typing . however , for navigation on the web , play music or video through Netflix and Amazon , I will continue to use my ioGear cordless keyboard with it be problematic , but much more intuitive roller , thumb-ball . this keyboard will also back up the old , ioGear cordless keyboard in case that stop work . Wireless keyboard become essential when one be sit 6 foot or more away from a hdtv , my 37 '' Vizio in this case , which I be use as a high-re monitor .
