Keybind Spaced Repetition - Learn keyboard shortcuts by actually typing them, with spaced repetition scheduling.

Built with Rust and ratatui, using the FSRS algorithm for optimal review scheduling.

Features

• Learn keybindings by actually typing them
• Spaced repetition scheduling via the FSRS algorithm
• Three keyboard modes: raw (Shift-g, Shift-4), chars (G, $), and command (ls -la, git stash)
• Multi-chord sequences like Ctrl+K Ctrl+C or y s i w )
• Visual feedback: green for correct chords, red for mistakes
• Pause/resume, card shuffling, session statistics
• Daily automatic database backups

Installation

Cargo

cargo install kbsr

Nix

For pre-built binaries, add the cache first (optional, avoids compiling from source):

cachix use kbsr

Then install:

nix run github:dbalmain/kbsr
# or install persistently
nix profile install github:dbalmain/kbsr

From source

git clone https://github.com/dbalmain/kbsr.git
cd kbsr
cargo install --path .

Quick Start

1. Create a deck file at ~/.config/kbsr/decks/my-shortcuts.tsv:

Ctrl+S      	Save file
Ctrl+Z      	Undo
Ctrl+Shift+Z	Redo
g g         	Go to top of file

2. Run kbsr, select your deck, and start typing keybinds.

Cards you get right are scheduled for future review. Cards you miss are repeated at the end of the session for practice, but only the first showing affects scheduling.

Terminal Requirements

kbsr uses the Kitty keyboard protocol for key detection. Supported terminals include Kitty, WezTerm, Ghostty, and foot. Running inside tmux will mean you can't study your tmux keybinds. Similarly, if you're practicing your window manager keybinds, you'll need to disable them somehow.
