My keyboard layout of choice for English is [Dvorak](http://en.wikipedia.org/wiki/Dvorak_Simplified_Keyboard). At work, I use [this keyboard](http://www.microsoft.com/hardware/mouseandkeyboard/ProductDetails.aspx?pid=095).
For certain tasks I’ve been involved in of late, I use emacs and often switch back and forth between buffers using control-x b. The x and b keys in dvorak are the physical b and n keys. These two keys are on separate halves of the keyboard, separated by the hump in the middle that contains the zoom thingy. This necessitates using both hands to execute the command.
Last night, I decided to do some work at home on my laptop (which does not have an ergonomic/split keyboard). When I went to switch buffers, I noticed that the b and n keys were right next to each other! It was strange.
