smt's Preonic keymap

This keymap is primarily based on the default Preonic keymap, which in turn is derived from Planck's default.

Notable differences from the default are:

  • Mod-Tap keys

    • Esc/Ctrl

      I am experimenting with using Left Shift as a mod-tap key for Escape, similar to how I use the Enter key. It's set up like this on my Minivan, so in the interest of consistency...

    • Enter/Shift

      I use both the left and right shift keys when I type. When I want to modify a key with shift, I hold shift with the hand opposite the one typing the key. In the default keymap, Enter is where shift would be on a standard keyboard layout. Oh, muscle memory.

    • Tab/Hyper (Super+Ctrl+Shift+Alt)

      It's great to be able to use Tab as a custom modifier key. I tend to use Hyper commands for various OS-specific operations depending on what machine I'm working on.

    • Backtick/Meh (Ctrl+Shift+Alt)

      Why use backtick in the lower left corner? I use it as my tmux prefix key, so I need to type it more frequently than most people. Putting it on the base layer works well for me. The "Meh" mapping is just a less-cool "Hyper"; the same, just without Super.

  • Swapped responsibilities of "lower" and "raise" layers

    I prefer to use symbols via the "raise" layer, and numbers via the "lower" layer.

  • Removed Plover layer

    I don't intend to use stenography anytime soon, so Plover just didn't have a place in my keymap.

Lower

This is where I put the number row, a numpad cluster, function keys, and media controls. Like the "Raise" layer, the top row is redundant to help with Planck compatibility.

Raise

As a developer, it makes the most sense for me to group all the commonly-used symbols that don't fit on the main layer. In particular, having the dual-column of parens-braces-brackets really helps a lot. I've also added cursorkeys to correspond to the arrows.

I haven't completely filled this layer, which leaves room for future mappings and macros.

Adjust (Lower + Raise)

Utility layer. This is where I'd switch between Qwerty and Dvorak, fool around with adjust the audio/music settings, or put the Preonic into bootloader mode.
