Selenium33

A Vim-friendly Arsenik mod:

• 3 home-row mods per hand for Ctrl, Alt, Super
• 3 layer-tap keys under the thumbs: Shift/Backspace, Navigation/Space, Symbol/Return

Selenium uses 4 layers (instead of 3 for Arsenik), which makes it a natural fit for 34-key keyboards like the Ferris.

Extended Navigation

• Vim-like navigation in all apps, with any OS layout
• super-comfortable Tab and Shift-Tab
• mouse emulation: previous / next and mouse scroll
• easy left-hand shortcuts

This Navigation layer has a few empty slots on purpose, so you can add our own keys or layers.

NumRow >> NumPad

In Symbol mode, pressing the left thumb key brings up the NumRow layer:

• all digits are on the home row, in the order you already know
• the upper row helps with Shift-digit shortcuts
• the lower row has dash, comma, dot and slash signs to help with number / date inputs

Even on keyboards that do have a physical number row, this NumRow layer can be interesting to use in order to minimize finger movements further more. And it makes it easier to mix symbols with numbers (e.g. [0]).
