Credits

• Hands Down Keyboard Layout
• The T-34 keyboard layout
• X-Case

Features

• Chord Mode - Type 220+ common words with just two letters! See the complete documentation for details.
• Design Philosophy - Learn about the hardware, ergonomics, and design principles behind this layout
• Home Row Mods - Modifiers on home row for ergonomic access
• Window/Tab Switching - Fast application and tab switching
• X-Case - Multiple case conversion modes (camelCase, snake_case, etc.)

Notes

• The keyboard layout is generated using generateKeyboard from this file. => link to Generator
• The generated keyboard can be found in the qmk directory.
• tested with Ferris Sweep keyboard

Home Row Mods

On all other layers, the modifiers are as shown in the table below.

Home Row Modifiers	Finger
Alt	Ring
Ctrl	Middle
Shift	Index

Window and Tab switching

• win ➡️ and tab ➡️ are used to Short windows and tabs.
• Once you press any of those keys, you're in switcher mode, where all other keys are replaced by shift-tab.
• Switcher mode is exited when you go back to the base layer.

Definition

How to read this layout:

• 💎 = combo key (e.g. middle and index finger in top row pressed together produce "b")
• 🛑 = key can't be used because the layer was activated with that key or because it's reserved for a modifier
• empty = use key from base layer
• FnSym = capitalized words are layer names - if they are a key, the layer is activated as toggled or one shot layer (if the "OneShot" flag is set in the layer flags)
• *Mouse = layer is active while key is held
• C-w = Ctrl-w (same for Alt and Shift)
• f12+Num = tab-mod - f12 on tap and Num on hold
• "that" = combo that produces "that"
• [ { = { is the shifted key of [, so it's used when Shift is held (only for information)
• The symbol table at the bottom shows the meaning of the symbols used in the layout.

Currently unused features:

• /+Ctrl = tab-mod - / on tab and CTRL on hold
• $Mouse = layer is active while key is held (double tap to lock layer)
• #Mouse = toggle layer
• @Num = layer is active for the next keypress
• Sym/Nav = layer is active for the next keypress: If the activation key is still down when the next key is pressed, the Nav layer is used, otherwise the Sym layer is used

Note: The layout is generated from this file directly.
