Hydra is an Emacs Lisp package that ties related commands into a family of short key bindings sharing a common prefix. Once invoked, the heads of a Hydra can be called repeatedly with single keystrokes until any other key exits the state, with on-screen hints showing available options.

Use cases

• create sticky keybindings for repeated commands in emacs
• bind zoom in/out to single keys after one prefix
• show a hint menu of related commands while editing
• chain navigation or window-management commands quickly
• replace repetitive prefix key sequences in my emacs config

When to choose

• you use Emacs and want efficient, repeatable key chords for related commands
• you want discoverable on-screen hints for your custom bindings
• you frequently run sequences of commands like resizing, navigation, or text scaling

When to avoid

• you don't use GNU Emacs
• you prefer modal editing solutions like evil-mode instead of prefix-based hydras
• you need bindings outside of Emacs
