An easy-to-learn, Optimot-based Corne layout

Dependencies:

• Layout: Optimot (choose Optimot ISO driver)
• Keyboard: Corne
• Firmware: ZMK

Keymap layers:

Features:

Leverages Optimot and its driver

• The Optimot layout is highly optimised for French and English secondarily
• It gives pride of place to alternating hands, rolling and avoiding collisions (see the documentation)
• Its driver provides with numerous ideally placed characters in secondary layers
• AltGr is in a key position to access them

Easy to learn, easy to swap

• Few layers
• Utility keys don't change between layers
• Close to a standard keyboard (learn your layout only once):
  • Familiar numbers and symbols layouts
  • Usual navigation shortcuts, yet more accessible
  • No dedicated key, homerow mod nor comboes

Mouse-friendly (right-handed)

• Utility modifiers heavily clustered on the left hand
• Mouse-support layer on the left hand (one hand) for natively two-handed shortcuts (ctrl+C, ctrl+V, etc)

Painless shortcuts

• Typing modifiers under the thumbs (SymNum, Shift and AltGr)
• Modifiers and layer switchers are easily comboed with fat thumbs
• Navigation and deletion are combinable with ctrl, shift and GUI

Limitations:

• AltGr+Space (non-breaking space) is not really possible, thus the dedicated key in the symbol layer.
• Caps-word doesn't stop with some punctuation characters (ZMK limitation due to the optimot layer).
• Shift+Alt+Tab is not really possible (Shift+Alt, in general).
• Browser navigation (Alt+left/right) is two-handed, but any mouse with five buttons or more will provide with it for the right hand.

Notes:

• Made for Linux; Windows should work; MacOS would require light changes.
• What is loaded as firmware (.keymap file) differs from the picture, as Optimot drivers modifies the QWERTY layout downstream.
• The gaming layer is entirely optional.
• Alt and GUI may be swapped depending on one's use.
• I am not affiliated with Optimot in any way.
