⌨ Toward a more useful keyboard

Features

A more useful caps lock key

By repurposing the anachronistic caps lock key, we can make control and escape accessible via the home row.

  • Tap caps lock for escape
  • Hold caps lock for control

📣 Shout-out to @arbelt and @jasoncodes for the implementation. ⚡️🍻🌟

(S)uper (D)uper Mode

To activate, push the s and d keys simultaneously and hold them down. Now you're in (S)uper (D)uper Mode. It's like a secret keyboard inside your keyboard. (Whoa.) It's optimized for keeping you on the home row, or very close to it. Now you can:

  • Use h / j / k / l for left/down/up/right respectively
  • Use a for option (AKA alt)
  • Use f for command
  • Use space for shift
  • Use a + j / k for page down / page up
  • Use i / o to move to the previous/next tab
  • Use u / p to go to the first/last tab (in most apps)
  • Use a + h / l to move to previous/next word (in most apps)

Window Layout Mode

Quickly arrange and resize windows in common configurations, using keyboard shortcuts that are on or near the home row.

Use control + s to turn on Window Layout Mode. Then, use any shortcut below to make windows do your bidding. For example, to send the window left, hit control + s, and then hit h.

  • Use h to send window left (left two thirds of screen)
  • Use j to send window down (bottom half of screen)
  • Use k to send window up (top half of screen)
  • Use l to send window right (right third of screen)
  • Use shift + h to send window to left 40% of screen
  • Use shift + l to send window to right 60% of screen
  • Use i to send window to upper left quarter of screen
  • Use o to send window to upper right quarter of screen
  • Use , to send window to lower left quarter of screen
  • Use . to send window to lower right quarter of screen
  • Use space to send window to center of screen
  • Use enter to resize window to fill the screen
  • Use n to send window to the next monitor
  • Use ← to send window to the space on the left (if there is one)
  • Use → to send window to the space on the right (if there is one)
  • Use shift + ← to send window to the monitor on the left (if there is one)
  • Use shift + → to send window to the monitor on the right (if there is one)
  • Use control + s to exit Window Layout Mode without moving any windows

Markdown Mode

Perform common Markdown-formatting tasks anywhere that you're editing text (e.g., in a GitHub comment, in your editor, in your email client).

Use control + m to turn on Markdown Mode. Then, use any shortcut below to perform an action. For example, to format the selected text as bold in Markdown, hit control + m, and then b.

  • Use b to wrap the currently-selected text in double asterisks ("B" for "Bold")

    Example: **selection**

  • Use c to wrap the currently-selected text in backticks ("C" for "Code")

    Example: `selection`

  • Use i to wrap the currently-selected text in single asterisks ("I" for "Italic")

    Example: *selection*

  • Use s to wrap the currently-selected text in double tildes ("S" for "Strikethrough")

    Example: ~~selection~~

  • Use l to convert the currently-selected text to an inline link, using a URL from the clipboard ("L" for "Link")

    Example: [selection](clipboard)

  • Use control + m to exit Markdown Mode without performing any actions

Hyper key for quickly launching apps

macOS doesn't have a native hyper key. But thanks to Karabiner-Elements, we can create our own. In this setup, we'll use the right option key as our hyper key.

With a new modifier key defined, we open a whole world of possibilities. I find it especially useful for providing global shortcuts for launching apps.

Choose your own apps

Hyper Mode ships with the default keybindings below, but you'll likely want to personalize this setup. See hammerspoon/hyper-apps-defaults.lua for instructions on configuring shortcuts to launch your most commonly-used apps.

Default app keybindings

  • hyper + a to open iTunes ("A" for "Apple Music")
  • hyper + b to open Firefox ("B" for "Browser")
  • hyper + c to open Calendar ("C" for "Calendar")
  • hyper + d to open Chrome ("D" for "Dev Browser")
  • hyper + f to open Finder ("F" for "Finder")
  • hyper + m to open Messages ("M" for "Messages")
  • hyper + n to open Notes ("N" for "Notes")
  • hyper + s to open Sublime ("S" for "Sublime")
  • hyper + t to open iTerm2 ("T" for "Terminal")
  • hyper + v to open Visual Studio Code ("V" for "VS Code")

Miscellaneous goodness

  • Use control + - (dash) to split iTerm2 panes horizontally
  • Use control + | (pipe) split iTerm2 panes vertically
  • Use control + h / j / k / l to move left/down/up/right by one pane in iTerm2
  • Use control + f toggle full-pane mode for split iTerm2 panes
  • Use control + u to delete to the start of the line
  • Use control + ; to delete to the end of the line
  • Use option + h / l to delete the previous/next word

Dependencies

This setup is honed and tested with the following dependencies.

Installation

  1. Grab the bits

    git clone https://github.com/jasonrudolph/keyboard.git ~/.keyboard

cd ~/.keyboard

script/setup

  2. Enable accessibility to allow Hammerspoon to do its thing [screenshot]

TODO

  • Add #13 to features:
    • Hold option for push-to-talk/push-to-mute
    • Double-tap option to mute/unmute microphone
