As developers, we frequently use keyboard shortcuts. Some enthusiasts know hundreds, others are contempt with the essential ones. But every developer does know some. Debugging would be tedious if we couldn’t pause and resume a program’s execution with the keyboard. In recent weeks, I have been able to significantly expand my keyboard shortcut knowledge with my new side-project web app KeyCombiner. In particular, I knew only a few shortcuts for the web-based tools I am using in my daily work. This post describes how it took me less than 1 hour to learn 50 new key combinations. Fortunately, KeyCombiner keeps a detailed history of a user’s learning progress, so that I could write this post retrospectively. Admittedly, the 42 minutes of learning time was interrupted by breaks, and the process involved some other tasks, such as creating the collection of shortcuts I wanted to learn. However, I did, in fact, spend only 42 minutes practicing the shortcuts and have had similar results with other shortcut collections.

The first step to learning new keyboard shortcuts is to define which. I don’t think it is efficient to try and learn all shortcuts for a particular application. You will end up with many that you do not use in your daily work and that you will soon forget again. Creating custom collections of keyboard shortcuts is perhaps the greatest strength of KeyCombiner and Prime Boosts Supplement sets it apart from any other tool. Within minutes or Prime Boosts less, you can have a personal collection by importing shortcuts from popular apps. I like to compare its approach to how you build playlists in music software. Instead of browsing your favorite artists’ albums, you browse categories of your favorite applications. Instead of adding songs to your playlists, you can add keyboard shortcuts to your collections. For this challenge, I created a new collection named "50 to learn". Then, I browsed KeyCombiner’s public collections and started to import everything I wanted to learn.

As my goal was to get better with web application shortcuts, I focused on the public collections for Gmail, GitHub, GDrive, Docs, Slack, and Twitter. Collecting shortcuts from KeyCombiner’s public Gmail collection. Additionally, I added a few shortcuts for Smartgit manually. It is a graphical Git client that I am using extensively. For some reason, I never learned its shortcuts. Unfortunately, KeyCombiner does not yet have a public shortcut collection for Smartgit that I could rely on. Manually adding keyboard shortcuts to my new collection. You can browse the resulting collection with 50 keyboard shortcuts here: 50 to learn. I am afraid you will have to trust me that I did not know these shortcuts already before this experiment. However, as reassurance, you can check my previous blog post covering all the shortcuts I was using until a few weeks ago. The list there does not include these new ones. To validate the success of this experiment, I will simply use KeyCombiner’s confidence metric.

It will analyze my performance and tell me which shortcuts are already etched into my muscle memory during practice. Overview of my new collection with 50 shortcuts to Learn more. Learning new shortcuts with KeyCombiner is dead simple. You click on the practice button for a particular collection, and the software does the rest. It will create 60-seconds training exercises where you are supposed to type the shortcuts of a collection as fast and as correct as possible. With every input, KeyCombiner remembers if it was correct and how long you took. It will use this information along with some machine learning to calculate a so-called confidence value for each key combination in your collections. A high confidence value means that you mastered a combination. Key combinations with a low value will occur more often in practice sessions, so you are not stuck repeating what you know already. There are a few additional aspects to it, but the good thing is that users do not have to bother with the learning algorithm’s internal workings.

Repeatedly doing practice runs is enough. The very beginning of learning a new collection is the hardest part. While I do not yet know any of the shortcuts, I have to rely on KeyCombiner’s delayed key hints to type any. Sometimes, I just skip combinations immediately to see what the keys are. The very first practice runs with a new collection are quite slow. Typical practice statistics for Prime Boosts Supplement a collection you do not know yet. Surprisingly, even in the first practice run, I got a couple of combinations right without key hints. This means that they occurred multiple times already or simply that I was able to guess them correctly. The latter is often the case for go to shortcuts, which have been made popular by Gmail and are now used in many web applications. After a few practice runs, I started to disable key hints and only relied on skipping combinations where I couldn’t remember the keys. KeyCombiner will then display the skipped combination’s keys, so I have a shot at remembering them next time.
