With the combination of hammerspoon and karabiner, we can do it with two simple keys. Most shortcut apps require you to press 3 or 4 keys each to resize windows and move between monitors. If you just install it, hammerspoon will do nothing,but what makes it so powerful is that you can write your own lua scripts or use one that has been written by the great open source community.The main reason I started using it is because I wanted a simple way to resize windows and move them between multiple monitors. Hammerspoon is a desktop automation tool for mac os and it job is to serve as the intermediary between the operating system and a Lua scripting engine, allowing you to interact with multiple mac os APIs. Make sure to allow karabiner_grabber and karabiner_observer.įor detailed installation instructions, you can see the installation docs here This can be allowed in Security and Privacy. You will be prompted to allow apps by the developer, and after installation is complete, you will be prompted for input monitoring permission. We can install Karabiner elements by running: If you quit Karabiner elements, your Caps Lock key will return to it's normal state. You can also customizer it to another key after trying this out. ![]() We're mapping it to the Caps Lock key because it’s use is limited as you can achieve the same functionality by holding down the shift key. Most developerers wouldn’t expect you to press five keys to run a shortcut. We use this four key combination because it is unlikely to interfere with existing shortcuts. This type of key combination is usually referred to as the “hyper key”. We’re going to be mapping the Caps Lock to command+control+option+shift. We will be taking advantage of this ability to change the behavior of the Caps Lock key. ![]() Karabiner Elements allows you to customize normal key behavior, and it’s complex modifications allow you to map multiple key combinations into one key. When I learned about the Karabiner Elements and Hammerspoon combo, I knew I needed to set it up, but my initial set up process ended up taking much longer than a simple installation, so I decided to outline the steps here in case this helps anyone. Here is what I wrote in the plex_les section of my karabiner.Do you ever find yourself wishing you could open your favorite mac os applications with a keyboard shortcut? Tired of pressing 3 to 4 keys to manage windows? Need to easily move a window to another monitor? Well, stop wishing because I’m gonna teach you how you can make this simple.Īs a keyboard shortcut lover, I’ve always enjoyed sharing my favorite shortcuts, and I’m always on the lookout for new ones. You would think I am crazy, but I just use Advantage2 with modified layout, so I have all these three keys under my left hand. Thus it is should be possible to use ctrl+tab and ctrl+enter+tab to switch tabs in Safari. if left_control is held down, return_or_enter works as shift.return_or_enter normally works as it should.I have posted this question as an issue on GitHub, but without much success. ![]() I am stuck with a problem with a non-trivial complex modification for Karabiner-Elements and I hope there are experts in this stuff here.
