I had to remove all of the keys on my "Tenkeyless Linear Touch 'Otaku' Keyboard". When I did so, I tried to sort the keys out, but I couldn't sort them all.
Putting it back together, I realized I made a huge mistake, and typing felt weird, because I had different heights on different rows that weren't supposed to be there.
Well, after some looking around on the keycaps I noticed something very important: there are letters on the underside of the keys, and they represent the height of the key. The higher the letter (towards Z) the higher the key height.
Here's a diagram of the correct heights according to the letters on the keyboard:
Hope this helps.
