Editing Alternative keyboard layouts (section)

==== Variations ==== 
From its inception AdNW has had several variations apart from the standard community release version. The other versions place slightly different weight to Dvorak's criteria (e.g. even lower adjacent finger use, at the expense of other criteria). Some of these variations are designed for different keyboards (matrix/orthogonal layouts, Ergodox, TEK etc.) or for other languages. A user can also calculate a custom layout.

Reasons for calculating a custom layout include: 
* Non-standard physical keyboard, for instance a Planck, a Space Cadet, a modded Ergodox or a DIY split keyboard
* Different preferences regarding finger use, alternation, and so on. Users may sacrifice performance on one aspect (e.g. alternation) in order to gain better performance on others (e.g. lower same finger use).
* Physical differences between users
* Input language. Users may not type 50/50 English-German prose, but for instance 30% French scientific prose and 70% Python code. 

All this can be combined: a user may calculate an optimal layout for "30% English prose, 40% Swedish forum use, 30% Polish, for Maltron keyboard, that avoids using the pinkies and that prefers the bottom row over the top row". Because of this freedom, there is not one single AdNW layout.

Some other examples of AdNW layouts are:
