For our purposes here, we're exploring Hammerspoon primarily in the context of using it to react to keyboard shortcuts and trigger something in response. Hammerspoon is an application you run in the background that loads custom Lua scripts to interact with your system, allowing you to script behaviors to react to system events. I dug deeper and deeper into the Hammerspoon ecosystem, looked at more custom Karabiner and Hammerspoon settings, and heard some feedback from my first post. In order to to try out global vi mode w/Karabiner, I had to sacrifice hyper+k from the Spectacle cheatsheet and switch that to be right-option+k. Additionally, tab can be rigged up to act as a modifier in conjunction with the hyper key to enable quick access to home/end/pgdn/pgup – which is especially awesome when you are on a laptop keyboard. With this Karabiner recipe enabled, you press a hyper key and then h/j/k/l to move the cursor left/down/up/right. Then, mid-way through patting myself on the back, I discovered global vi mode with a hyper key and Karabiner. I like keyboard shortcuts bound to keys based on a pnemonic, so binding my global spectacle keyboard shortcut cheatsheet to hyper+k seemed like a good, quick win that would help me memorize those Spectacle shortcuts.

Having an extra meta key with a whole slew of nonconflicting keybinding slots seemed awesome. I had combed through many blogs and git repositories.

Automatically pause audio playback when headphones are unplugged.

Keep a configurable and persistent clipboard history.

Keyboard-triggered translation of selected text between arbitrary human languages.

Set up actions to happen automatically when switching between WiFi networks-for example, for reconfiguring proxies in some applications.

Replace Spotlight, Lacona and other launchers with a fully configurable, extensible launcher, which allows not only to open applications, files and bookmarks, but to trigger arbitrary Lua functions.

When combined with Site-specific Browsers, this allows for highly flexible management of bookmarks, plugins and search configurations.

Dispatch URLs to different browsers based on regular expression patterns.

#Hammerspoon hyper key windows#

Manipulate windows using keyboard shortcuts to resize, move and arrange them.For example: automated tagging and filing in Evernote, mail archival in Mail or Outlook, filing items from multiple applications to OmniFocus using consistent keyboard shortcuts, or muting/unmuting a conversation in Skype. Add missing or more convenient keyboard shortcuts to applications, even for complex multi-step actions.Here are some examples of things you can do with it:

#Hammerspoon hyper key mac#

Using Hammerspoon, you can replace many stand-alone Mac utilities for controlling or customizing specific aspects of your Mac (those that tend to overcrowd the menubar). Hammerspoon configuration is written in Lua, a popular embedded programming language. It also allows interfacing with AppleScript, the most common mechanism for automation on the Mac. It enables interaction with the system at multiple layers-from low-level file system or network access, mouse or keyboard event capture and generation, all the way to manipulating applications or windows, processing URLs and drawing on the screen. In this book you will learn how to use Hammerspoon, a powerful open-source framework which makes using a Mac more pleasant, productive and fun.
