A reasonably comprehensive collection of known logical (as opposed to physical) letter layouts for computer keyboards.

These alternative computer keyboard layouts are mostly for English, but there are a few other languages as well.

The table is sortable, searchable and expandable. The Search box is very useful.

The layouts are named as name.language.format.

Layouts marked with have been analysed. The others are either development or minor versions, or bad for your hands or head, and just have an image and KLA json.
