Application Config

Ghostty

Partial config snippet to add to your Ghostty config file (located at ~/.config/ghostty/config by default).


# sends ESC d, which Zsh/Bash typically interpret as kill-word (delete next word).
keybind = alt+delete=esc:d
iTerm2

These custom key mappings will allow movements using arrow keys in conjunction with modifier keys. The following JSON can be added to your iTerm2 key bindings under Settings → Keys → Key Bindings → Presets... → Import...

Hammerspoon

Partial config snippet to add to your Hammerspoon initialization file (located at ~/.hammerspoon/init.lua by default). Used in conjunction with Karabiner-Elements to detect lock screen.


local karabinerLog = hs.logger.new("karabinerSync", "info")

local KARABINER_CLI = "/Library/Application Support/org.pqrs/Karabiner-Elements/bin/karabiner_cli"

-- Push a variable into Karabiner-Elements so complex modification rules
-- can react to it via variable_if / variable_unless conditions.
local function setKarabinerVariable(name, value)
  local json = string.format('{"%s": %d}', name, value)

  local task = hs.task.new(KARABINER_CLI, function(exitCode, _, stdErr)
    if exitCode ~= 0 then
      karabinerLog.ef("karabiner_cli failed (%d): %s", exitCode, stdErr)
    end
  end, { "--set-variables-from-stdin" })

  task:setInput(json)
  task:start()
end

-- Keep Karabiner's `is_lock_screen` variable in sync with the real lock state,
-- since Karabiner has no native way to detect this itself.
local screenWatcher = hs.caffeinate.watcher.new(function(eventType)
  if eventType == hs.caffeinate.watcher.screensDidLock then
    setKarabinerVariable("is_lock_screen", 1)
  elseif eventType == hs.caffeinate.watcher.screensDidUnlock then
    setKarabinerVariable("is_lock_screen", 0)
  end
end)

screenWatcher:start()
Automator

Use the following AppleScript Quick Action to toggle Dark Mode on macOS; created via Automator. This service can be assigned a keyboard shortcut (ctrl+opt+cmd+D for Serenity QMK Hardware Layer) in System Settings.


on run {input, parameters}
	tell application "System Events"
		tell appearance preferences
			set dark mode to not dark mode
		end tell
	end tell

	return input
end run

Reference

Vim-less

Thinking of quitting Vim? Here is an indicative reference for performing common Vim-like motions/commands by effortlessly using standard keybindings (primarily made possible with QMK due to Mod and Arrow key availability on the home row). These shortcuts are application-agnostic and eliminate the need for a modal editor for most tasks, or, at a minimum reduce the reliance of using Normal Mode, allowing you to remain in Insert Mode more often than not.

Some of the other commands and movements not covered by the basic movements can often be implemented in modern text editors via extensions or built-in functionality. Here are a couple of VSCode Extensions I maintain to fill in some functionality gaps so to speak.
