# The BDK Ergodox Keyboard Layout
## Dvorak-based
This was the first alternative layout I switched to and I don't want to change
again.
## Mod-tap / Layer-tap is great for thumb keys
This means a key that activates a layer/modifier when you hold it down, but
results in a keyclick when you tap it. Thumb keys are great for this since
they are good for both high-usage keys as well as modifiers.
The one thing to avoid is when you mean to tap a key, but hit the next key
before you release, which results in the modifier/layer instead of a tap. To
avoid this, I chose Enter/Tab as the tap keys, since they aren't chorded
together with other keys often.
The other issue is I found several problems with using the standard MT,LT code,
so I rolled my own to handle it.
## Don't have too many layers
My first layouts had multiple layers that I could switch to, but that
overloaded my brain. This layout basically only uses 1 extra layer.
Technically there's also a function key layer, but I only use those keys for
a handlful of things: boot order, rename, reload page, that's basically it.
## Brackets should be easy to use
There's a lot of ways to lay out a symbol layer. I organized mine around
making the {[()]} chars easy to use since they're so frequent in programming.
I put them all on the symbol layer home row.
I also arranged the numbers so 0/1 were also on the symbol layer home row.
This makes for fairly easy chording of "[0]" and "[1]".
