Toward a more useful keyboard

Steve Losh's Modern Space Cadet is an inspiration. It opened my eyes to the fact that there's a more useful keyboard hidden inside the vanilla QWERTY package that most of us have tolerated for all these years. This repo represents my nascent quest to unleash that more useful keyboard.

At first, this might sound no different than the typical Emacs/Vim/<Every-Other-Editor> tweakfest. But it is. I'm not talking about honing my editor-of-choice. I'm not talking about pimping out my shell. I want a more useful keyboard everywhere. Whether I'm in my editor, in the terminal, in the browser, or in Keynote, I want a more useful keyboard.

And ideally, I want the same (more useful) keyboard in every app. Ubiquitous keyboarding. Muscle memory. Don't make me think.

How do I go to the beginning of the line in this app? The same way I go to the beginning of the line in every app! Don't make me think.

How do I go to the top of the file/screen/page in this app? The same way I... Well, you get the point.

More useful (for me)

cus·tom·ize (verb): to modify or build according to individual or personal specifications or preference [dictionary.com]

Any customization is, by definition, personal. While I find that these customizations yield a more-useful keyboard for me, they might not feel like a win for you.

Features

Access control and escape on the home row
Navigate (up/down/left/right) via the home row
Navigate to previous/next word via the home row
Arrange windows via the home row
Enable other commonly-used actions on or near the home row
Format text as Markdown
Launch commonly-used apps via global keyboard shortcuts
And more...

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)

📣 Shout-out to Karabiner's Simultaneous vi Mode for providing the inspiration for (S)uper (D)uper Mode. ⌨:neckbeard:✨

Window Layout Mode

Quickly arrange and resize windows in common configurations, using keyboard shortcuts that are on or near the home row. (Or, feel free to choose your own keyboard shortcuts.)

Default keybindings

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 half 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 half 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 u to send window to upper left quarter of screen
Use i to resize window to a quarter of the screen and center at the top
Use o to send window to upper right quarter of screen
Use , to send window to lower left quarter of screen
Use . to resize window to a quarter of the screen and center at the bottom
Use / to send window to lower right quarter of screen
Use space to resize window to 80% of screen width and center it
Use g to resize window to 80% of screen width and align to the left
Use ; to resize window to 80% of screen width and align to the left
Use enter to resize window to fill the screen
Use t to resize the top of the window to the top of the screen
Use b to resize the bottom of the window to the bottom of the screen
Use n to send window to the next monitor
Use ← to send window to the monitor on the left (if there is one)
Use → 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

Choose your own keybindings

Window Layout Mode ships with the default keybindings above, but you're welcome to personalize this setup. See hammerspoon/windows-bindings-defaults.lua for instructions on configuring shortcuts to your personal taste.

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

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 + 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.

macOS Big Sur, 11.6
Karabiner-Elements 13.7.0
Hammerspoon 0.9.90

Installation

Grab the bits

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

cd ~/.keyboard

script/setup

Enable accessibility to allow Hammerspoon to do its thing [screenshot]
You'll be prompted to allow Karabiner-Elements to load its kernel extension, followed by a flurry of prompts related to input monitoring. Follow the prompts to upgrade your life.
