Kbar
kbar is a React command palette library that gives applications a searchable overlay for finding and executing commands using the keyboard. It includes keyboard shortcut binding, so users can trigger commands directly without opening the palette, and supports nested sub-menu navigation, allowing actions to be organized into hierarchical groups that can be drilled into and back out of with arrow keys.
The library differentiates itself through a hook-based API that lets any React component register commands and shortcuts declaratively, alongside a global keyboard listener that handles palette activation and shortcut dispatching from a single point. It maintains an action history stack for smooth navigation between menu levels, and applies priority-based sorting so frequently used commands surface earlier in search results. State is shared across the component tree via React Context, enabling all descendants to read and update the palette without prop threading.
