From the project
Family of split ergonomic keyboards with three rows of six or five keys and a generous thumb arc
Hillside 46 is a split ergonomic keyboard with 3x6+5 choc-spaced keys. It has the aggressive stagger of the Ferris plus finger splay, a longer thumb arc and break-off outer pinkie columns.
Splaying the columns lets our fingers more naturally follow our hand mechanics. See the Hillside family readme for features common to all hillside boards. Specific to the Hillside 46 are:
