Improve your Vim Skills with KeyCombiner for free

Hi HN!

KeyCombiner is a web app to organize, learn, and practice keyboard shortcuts as well as short text snippets. As of today, it has a public collection of Vim Shortcuts than can be used for learning and for testing your skills.

You can learn public collections, or better yet, create personal shortcut collections by importing selected shortcuts from public collections or by defining your own key combinations.

There are two training modes:

1. Learn: Expand your shortcut knowledge flashcard-style. You can choose if KeyCombiner should show you the keys to type along with the description or configure a delay, giving you some time to think.

2. Test (your skills): Type shortcuts and text snippets from memory as fast as possible. KeyCombiner will create statistics, showing you where you make mistakes and which shortcuts take you longer than others. It uses test results to calculate a confidence score for each or your key combinations.

It is free to use. This is the first time I publish an app, any and all feedback would be highly appreciated!
