# 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](https://github.com/jackhumbert/qmk_firmware/wiki#fun-with-modifier-keys) keys, and this allows me to set the Enter key to send a modifier (MOD_LSFT) when held, and KC_ENT when tapped. Awesome!

## 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.
