let I start off by describe what the happy hacking keyboard -lrb- hhk from now on -rrb- be : the hhk be a small keyboard by any standard , the layout be reminiscent of Sun 's System 5 keyboard , where the control key be located where the cap lock usually be . the small form factor be achieve by place the ESC key be just to the left of the `` 1 '' key -lrb- as oppose to be to left of the f1 key , sometimes with a gap in between -rrb- and the Back Space be just over the enter key -lrb- as oppose to be next to the '' = '' key -rrb- also the arrowkey , pg up\/down , insert and delete key , Prt Sc , Scroll Lock and Break key be access via the Fn key and one of the letter key on the right side of the keyboard -lrb- I , O , p , K. L , etc. . . -rrb- . most of the feature of the hhk can be alter via the dip switch on the back , where you can decide if the Delete key will really be a delete -lrb- and delete forward -rrb- or a typical backspace . if you can not take the control key be where it be , or if you use the cap lock function regularly you can also change that with the dip switch . there be many other option you can change , and I would advise anyone who feel reluctant with the HHK 's layout to do a quick google search prior to the purchase and check all the possible combination of those switch . it have a usb connection -lrb- female on the keyboard , so it be detachable -rrb- and two usb port to plug in peripheral . I own ten of keyboard with vary degree of collectability and , to be honest , usability . about a year ago I purchase a hhk Lite -lrb- similar to the pro 2 when it come to layout , although my version have dedicate arrow key -rrb- and I it feel like home in term of key placement , I be unix\/linux user for the most part and have the control key `` right there '' and the ESC key just a inch away from my pinky be simply perfect -lrb- if you be a vim\/emacs user you 'll certainly appreciate that -rrb- . the Lite version however be somewhat sub-par in term of quality , the pro 2 be simply in another league and I 'll talk about that later in the review . it never stop I from swap keyboard every time I have the chance , but I always come back to the hhk Lite . so what can you expect from you first few typing session with a hhk ? as soon as you lay you hand on the keyboard and start typing the first oddity be the backspace key , it be simply not where you would expect and it take some time to get use to it be just over the enter key . curiously I adjusted very quickly to have the control key just to the left of my pinky . the lack of cursor key be not a big problem for I , although you milage may of course vary , so do take that into account . the only think I can vouch for regard the arrow key be that press fn and then the letter for the correct arrow become second nature and to be honest the position of the Fn key guarantee that the `` chord '' do not feel awkward . of all the keyboard I own the keycap on the pro 2 be simply the best I have ever experience , it be hard to explain how they have just the right amount of `` grain '' to make you feel you finger be hold on to something , but at the same time it do not hold they back at all , the plastic feel solid and like something very likely to survive a nuclear holocaust and subsequent fallout , curiously if you pick up the keyboard if feel fairly light though solid in construction . the electronics be as good as they get these day -lrb- though some might argue that dip switch be terribly old fashion and that with this price tag be certainly could have some internal memory to store setting -rrb- , the HHK use Topre switch , the mechanism use a spring shape like a cone , accord to the maker of the keyboard it allow a better feel and a longer lifespan . BTW , just because it be a mechanical keyboard do not mean it be a `` clicky '' keyboard , it be not , it be not much noisier than you stock keyboard , though if I have to describe the sound it be a bit lower -lrb- frequency wise -rrb- than one would expect , and it sound `` compress '' . this be obviously a very personal opinion , but I like it . as a quick reference , the Lite version be not mechanical , the electronics be not nearly as good and the plastic on the keycap be not any better than whatever keyboard come with you desktop computer , for the price the Lite be not all it be crack up to be and unless you be hook on the HHK 's layout there be certainly better option out there for about the same buck . I can not really rave enough about the HHK pro 2 , it be a wonderful keyboard load with feature and it ooze this feel of be a boutique keyboard . ... but man , that be a steep price tag !
