My personal keyboard layout for OWLab Link65, Vertex Arc60, Ai03 Meridian, Haven 60, and Gray Studio bd60. Keyboards are all 60/HHKB layout except OWLab Link65.
Note: I'm using arc60 welding version now. arc60h is archived.
I believe that use left hand to do most frequent things.
First layer ---> Symbol layers, include arrow keys. Second layer ---> Mouse keys and Super keys combination. Third layer ---> F-Keys (F1 ~ F24) with Ctrl, Shift, Alt mapped in a more convenient way, and some system functions. Fourth layer ---> Left-hand arrow keys, for document navigation keys in normal text editors. Fifth layer ---> The enhancement of the right-hand arrow keys, windows management and F-Keys.
Layers here are not necessary. Sixth layer ---> Basic layer with arrow keys. (gaming) Seventh layer ---> Backup layer
