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

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

Features:

• Mouse-friendly (right-handed)
  • Utility modifiers heavily clustered on the left hand
  • A mouse-support layer on the left hand
• Easy to learn, easy to swap
  • Few layers
  • Utility keys don't change between layers
  • Close to a standard keyboard (learn only once):
    • Familiar numbers and symbols layouts
    • Usual navigation shortcuts, yet more accessibles
    • No dedicated key nor homerow mod
• Painless shortcuts
  • Text modifiers under the thumbs (SymNum, Shift and AltGr)
  • Modifiers and layer switchers are easily comboed with fat fingers
  • Navigation and deletion are combinable with ctrl, shift and GUI
• Leverages Optimot and its driver
  • The Optimot layout is highly optimised for French and English secondarily
  • Its driver provides with many ideally placed characters
  • AltGr is in a key position to access them

Limitations:

• AltGr+Space (non-breaking space) is not really possible
• Caps-word doesn't stop with some punctuation characters (ZMK limitation)
• Shift+Alt+Tab is not possible (Shift+Alt, in general)

Notes:

• Meant for Linux; Windows should work; MacOS would require light changes.
• What is loaded as firmware 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
• The left hand mouse-support layer does not feature browser navigation, but any mouse with five buttons or more will have it
