This is a neat concept!<p>One not-so-obvious accessibility issue with keyboard shortcuts on websites is that if they're too simple (especially single-character), it's easy for them to conflict with assistive technologies like screen readers.<p>Maybe consider including a pointer to <a href="https://www.w3.org/TR/WCAG21/#character-key-shortcuts" rel="nofollow">https://www.w3.org/TR/WCAG21/#character-key-shortcuts</a> in the docs (and/or as some sort of warning message if a user tries to configure a custom single character shortcut).
Hey Sergei, are you Keyboard Ninja?<p>This will be off topic, but can you list your software that you use to make everything keyboard friendly?<p>I personally use Keypirinha as my launcher, Total Commander as my file manager, and Firefox with Vimium-C extension as browser.
