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:

1. Dvorak by default

   I happen to type in Dvorak, and prefer that layer to be the default on my keyboard. This is easy enough to switch around with Qwerty, Colemak, or whatever.

2. Right 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.

   Thankfully, QMK supports mod-tap keys, and this allows me to set the Enter key to send a modifier (MOD_LSFT) when held, and KC_ENT when tapped. Awesome!

3. Escape

   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...

4. Backtick

   I don't currently have LEDs on any of my keyboards, and even if I did, I don't think I would want their controls on a base layer.

   So, 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.

Lower

This is where I put the number row, a numpad cluster, function keys, and some light navigation via Home/End/PageUp/PageDn. 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 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 to Qwerty, or fool around with adjust the audio/music settings.
