Frequently Asked Questions

KeyCombiner is a web application that lets you organize, learn, and practice keyboard shortcuts as well as short text snippets. In the context of KeyCombiner, both are called key combinations.

We all know that the use of keyboard shortcuts is more efficient than relying on a mouse. It is also gentler on our hands, helping to protect against medical conditions, such as tendonitis. However, it is tedious to keep track of all the different keyboard shortcuts in the large amount of tools that many of us are using. The first goal of KeyCombiner is to help you get an overview of all the combinations you could use and define collections of combinations that you actually want to use.

The second goal is to help you learn and memorize these combinations. And finally, KeyCombiner helps you build muscle memory to achieve the ultimate goal of being able to use many combinations from memory, fast, and correctly.

Unfortunately, learning all shortcuts of all applications we use is a tall order, even with KeyCombiner. That's why KeyCombiner Desktop enables you to instantly look up all shortcuts that are in your combined collections plus those of the currently active application.

Then there is a variety of additional features, such as sharing your collections with friends and co-workers, and exporting them to different formats. We also have have a public keyboard shortcut database that can be searched as a whole or browsed per application. Head over to the Features for a full list.

In short, you will want to use KeyCombiner if you value keyboard shortcuts and want to get even better at using them.

We have a paid plan that comes with a multitude of additional features. While we are committed to provide the core functionality for free in order to promote efficient keyboard usage, we need paying customers to support our hosting and development efforts. If you like this service and want it to become even better, please consider upgrading to a Pro subscription.

If you are a company looking for custom sponsorship or advertising opportunities, this would help us too!

All of them!

KeyCombiner goes to great lengths to support international layouts as good as possible. However, it's impossible for KeyCombiner to provide better keyboard layout support than the target application for which you are learning or looking up shortcuts for. If the target application uses keys in its shortcut definitions, that cannot be typed with your keyboard, we have to improvise.

Most shortcut combinations should work on all layouts, text snippets even more so. Some keys will cause problems on non-US layouts, such as =, / and \.

KeyCombiner provides several solutions:

  • Use key aliases. KeyCombiner lets you set aliases for keys that do not exist on your keyboard layout and require the use a modifier key. For example, on a German keyboard, you might want to set Shift+7 as an alias for /. KeyCombiner will then listen for Shift+7 whenever / occurs during practice.
  • Use KeyCombiner to edit and re-record the combination with your own keyboard. For example, on German layouts, ctrl+* will then be ctrl+shift++. This approach guarantees that the combination works flawlessly during practice since you have recorded it with the exact same keyboard layout.
  • As a last resort, you can exclude any combination from practice by adding an underscore, e.g., _ctrl+/.

These workarounds have proven sufficient even for power users who have mastered hundreds of shortcuts!

Chances are you are using macOS and must grant some permissions to KeyCombiner so it can find out which application is currently active. Please read the installation instructions at the bottom of our page for KeyCombiner desktop.

The instant lookup works on all platforms: Windows, macOS, and Linux!
