ZMK Config

Philosophy

• heavily inspired by urob config (combos > layers)
• common symbols for JS/TS are prioritized (some deviaton from urob config here)
  • Brace is available on bottom row, bracket on top row. I keep a dedicated backspace and don't really use delete (I use x in vim)
  • Swap back vertical combo & to be below 7 with | below - I do more logical compares than maths so this made sense for my use and it follows the number symbol row more closely
  • Horizontal combos on the left middle row for undo, redo, and select all. Along with cut/copy/paste (bottom row combos) this allows for most text related actions I need while using a mouse, all on left hand.
• homerow mods ("Timeless" per urob) Homerow follows ACGS mods
  • This leaves my tiling window navigation keys (Gui, Gui + SHIFT) close by (* see OS Accommmodations below)
• navigation layers
  • with the tiling window shortcuts above, i have the space and move layers set up for single handed window movement if needed (eg, while using mouse)
• Key / shift remap (per urob)
  • ? / ! are combined, with f slash (/) available via combo (per urob)
  • , / ; and . / : on tap, shift tap. < / > are available as shifted parens combos (homerow)
• Macros
  • javascript function macros on top, bottom rows via combo. these place the cursor inside the parens.
• vim like nav on base/nav layers

OS Accommodations

• Mods - Karabiner remaps Gui -> Ctrl and Ctrl -> Gui, this keeps consistent mod "intentions" across OS

Layer Explanation

• combos are available on base, nav, num layers.
• num layer provides a southpaw numpad.
• nav layer overlays arrow keys over hjkl for easier navigation in non-vim settings. The numpad also has LG() applied to all numbers for space changing. there are shortcuts for alfred and mission control on the homerow.
• mv provides single handed window space movement (mod+shift applied over num layer). This is accessed via a double tap of the NAV layer key.
• util is a conditional layer triggered by activating num/nav. this is a bit of a dumping ground for os/media/zmk utils.
