LanguageProject Introduction
Summary
keyd is a lightweight yet powerful Linux daemon designed for comprehensive key remapping and keyboard customization. It runs in the background, allowing users to define highly specific behaviors for their input devices.
Problem Solved
Standard Linux key remapping tools often lack the flexibility, per-device customization, and advanced features (like layers and complex macros) required by power users or for specific hardware setups. keyd addresses these limitations by providing a powerful, daemon-based solution.
Core Features
Per-Device Keymaps
Allows defining different keymaps for different keyboards or input devices connected to the system.
Layer System
Enables switching between multiple mapping layers (e.g., default, function, custom) using modifier keys or dedicated layer keys.
Advanced Binding Syntax
Provides a flexible configuration syntax to create complex key bindings, including macros, sequences, and conditional actions.
Tech Stack
C
Linux Kernel (input subsystem)
Systemd
使用场景
keyd can be applied in various scenarios where standard key mapping falls short, enabling personalized and efficient interaction with your Linux system.
场景一：优化日常键盘布局
Details
Map Caps Lock to act as Control when held, and Escape when tapped. Create a layer accessible via a modifier key (e.g., AltGr) for media controls or special symbols.
User Value
Enhance typing comfort and speed by customizing frequently used keys and adding convenient access to secondary functions.
场景二：定制游戏或专业硬件
Details
Configure a dedicated gaming keypad (like a Tartarus or Orbweaver) to have custom key bindings and macros tailored for specific games or applications, using its unique device ID.
User Value
Unlock the full potential of specialized hardware by assigning complex actions or application-specific bindings directly to its keys.
场景三：自动化工作流程
Details
Define keyboard shortcuts that execute complex command sequences or scripts, triggered by a single key press or combination.
User Value
Streamline repetitive tasks and improve productivity by turning multi-step operations into instant keyboard commands.
