// readme
// This keyboard layout is based on the [Workman Dead layout](https://github.com/ojbucao/Workman/tree/master/mac#workman-dead-for-programmers), which uses the comma as a dead key to trigger a second layer.
// Since I have more keys at my disposal on the ErgoDox, I moved the dead key to the bottom right. There are still a lot of
// blanks so still discovering what I like.
// If you aren't familiar with a dead key, the idea is that you tap the dead key which switches the layout. the next key you hit
// triggers the key you pressed AND switches the layout back to the original. For now I do this with a super kludgey macro and I
// look forward to learning about a more elegant way to do the same thing. Until then, this will have to do.
