Editing Region-specific layouts (section)

===Background===
Common differences in physical keyboard designs over the world are those between '''[[ISO]]''' (“International”), '''[[ANSI]]''' (American) and '''[[JIS]]''' (Japanese). 

On the ISO keyboards, the Enter key is vertical (sometimes termed an “ISO Enter”) and the left and right Shift keys are an equal distance from the traditional [[touch typing|home position]].

On the ANSI keyboards, the Enter key is horizontal and the Left Shift is wider, placing it much closer to the centre than the Right Shift. Traditionally, American-based layouts also lack an Alt Gr, and instead have a simple Right Alt which performs the same function as the Left Alt.

On Japanese keyboards, the ISO-style Enter and Left Shift are normally accepted, and the Backspace and Right Shift are both shortened by one key. In addition to this the space bar is shorter to accommodate more keys on its row.
