# 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](https://github.com/jackhumbert/qmk_firmware/wiki#fun-with-modifier-keys) 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](http://brettterpstra.com/2012/12/08/a-useful-caps-lock-key/) 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.
