![]() Pressing d will activate the layer with g and y.Īt each level, a helper text is shown, like which-key in emacs. Here, pressing option+space activates the first layer with b, t, d (browser, terminal, domain respectively) hs.loadSpoon("RecursiveBinder") - Load the spoon Here is a minimal lua snippet on how to use it. I wrote a Medium article about how to use it to make a leader key for macOS. There's a few features in there now that I am not covering in this post, but we'll get to them later in this series.If you're still wondering how to do this, then the RecursiveBinder Spoon for Hammerspoon will do the trick. It's possible it's gone through new versions since this post. If you want to read a at the time of this blog post, it's available on my GitHub. No more discovering that weird app behavior is due to a double-bound keybinding.Īs this series continues, I'll list the examples of how I connect a to other automations here. In button-press conditions, this contrast revealed a peak activation in MCC. All my keybindings are declared in one place, and I know they will never conflict with any new applications that I download. and hammer/spoon stimuli oval encircles the part of the implement shown. ![]() I use a as the "entry point" for nearly all my Hammerspoon based automation. My most common use of a is to launch an application, so I have a table of applications that I can define a "hyper key" for, and optionally some local bindings that I bind inside that application to use globally. hyper : bind (, 'r', nil, function () hs. Press `HYPER+r`, get the Hammerspoon console. Because your "hyper key" is not a cluster of modifier keys, you can actually use it in conjunction with any normal modifiers. One big advantage to using Hammerspoon as a "man-in-the-middle" is using modifiers with your hyper key. Brett Terpstra first wrote about this in "A Useful Caps Lock Key" in 2012. In this as in all things, I am not the first. Instead of having every single application listening to all the keystrokes, I can control it one place. ![]() I use a single often-unused key (in my case, F19) to trigger a hs.hotkey.modal in Hammerspoon. In my case, Hammerspoon becomes a single "router" to all the automation and UI customization on my Mac. The hotkey can be single key (For example, F1) or combo-key (For example. Assign hotkey to launch/switch/open apps or files. Using a single keycode as your "hyper" key, and handling the translation at the automation layer is much more expressive. App launchers are primarily designed to launch apps, open files, run scripts.You set a key to do them, or, a hotkey that pops up a dialog, then type any letter to launch or search. Because of this a lot of hyper key setups are limited to "leader key" style interactions. Using the "hyper chord" as the entire "hyper key", you can't add any more modifiers, because it is already all the modifiers. While it works well, it has its limitations. ![]() You can absolutely do this in Hammerspoon if you want. With Hammerspoon it is incredibly easy to bind Hyper Mode shortcuts to Applescript files ( a feature I contributed to ). 3.2 Applescript Many macOS applications export part of their functionality with Applescript. For example, your computer may say something like Press F9 to configure BIOS. During this process, you can press a specific key combination to configure this layer of software. When your machine boots up, before the operating system is loaded, the BIOS/UEFI initializes the system. The user would then use some kind of automation software like Alfred or Keyboard Maestro to listen for the "hyper chord" and fire different automations. Which tells Hammerspoon to send out the corresponding keystroke when pressing Hyper + U. Anish’s Hammerspoon config Booting + Live USBs. Traditionally, a Hyper key is implemented by sending to the Operating System "hyper chord" of ⌘⌥⇧⌃ by modifying the keyboard firmware or using Karabiner-elements.app. The code isn't that complex so this post will be focused on the advantages of this approach. I'm using hs.hotkey.modal to capture an F19 keystroke, and only sending the "hyper chord" of ⌘⌥⇧⌃ if absolutely required. At the moment, my hyper implementation is contained in a lua module called a, with some dependencies on Karabiner-Elements.app. I talked in the last post about my history with the concept, how I learned from Steve Losh's post on the topic and borrowed from Brett Terpstra… and I've expanded the idea a bit.
