# 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]".
