Highly flexible keyboard shortcut management for any environment.
This library focuses on providing the data-structure and building blocks necessary to allow you to build probably™ anything you can think of regarding shortcuts.
It does so by adopting a code-over-config approach, a range of utility functions that come with no side-effects, or any default behaviour. You are in control of how to parse shortcuts, how to register them, how to match them against keyboard events and how to execute them.
Sometimes keyboard shortcut management can get a little bit complicated:
- Custom shortcut parsing
- The provided ones may not correctly detect certain keys
- You would like to use an alternative syntax such as VIM-style shortcuts (
<c-w><left>) - Custom aliases
- Custom event handling
- You would like to ship shortcuts in non-browser environments such as react-ink, or terminals
- You would like to programmatically trigger shortcuts
- High control over browser event handling
- Binding to
document, a focusable element, React refs, React callbacks, third-party libraries, … - Listening to
'keydown','keyup','keypress','input','beforeinput', with or without{ capture: true }, …
- Binding to
- Telemetry
- Tracking shortcut usage
- Tracking attempted shortcut usage (shortcuts that have been tried, but not yet implemented)
- Resolving shortcut conflicts
- Throwing Exceptions
- Or using different strategies such as priorities, scopes, layers
- Building a UI around shortcuts
- Recording and replaying keypresses
- Filtering out certain keypresses
- Error handling
- Attaching additional meta-information such as the shortcut
- Sequence management
- Emulating VSCode's behaviour (Infinite timeouts, warning message for invalid sequences)
- Emulating VIM's behaviour (
timeoutlen,nowait, canceling partial sequences withesc)
- Grouping shortcuts together using scopes, enabling/disabling scopes, etc.
- Disabling specific shortcuts under certain conditions
- Different keybindings enabled only for MacOS/Windows
- Support for sticky keys for accessibility reasons
- Pausing and resuming event listeners
- Skipping between
CompositionStart&CompositionEndevents - Support user-provided
{ 'ctrl+a': 'CommandName' }configs similar to VSCode or Zed - Emulating Emacs' or VIM's concept of (sub)modes (eg. Hydra.nvim)
As I have been frequently hitting brick walls trying to go for any of the above, I set out to create this 📦!
