I've used a US-QWERTY keyboard layout my entire life. I've seen other layouts that do things like reduce the size of the enter/backspace keys, move the pipe operator (|) and can't wrap my head around how I would code on those.
What are your experiences? Are there any layouts that you prefer for coding over US English? Are there any symbols that you have a hard time reaching ($ for example)?
Why are there two cables connecting the left and right part? Just curious.
I believe the lower cable connects the two boards. The upper cable is for connecting to your device, so would only be connect to one of the boards when in use.
For looks. The middle cable is needed to allow the sides to communicate, but you only need one side plugged into the computer.
