It exists because desktop-specific tools such as xmodmap and xcape can be brittle across X11, Wayland, terminal VTs, and multiple keyboards. ### 项目历史 The project, maintained by rvaiya, framed its impetus as a missing Linux-wide remapping solution. Its design goals are speed, a simple config format, consistent modifier behavior, and a small Unix-style daemon with IPC for scripting and application-specific remapping. The v2 documentation notes that the configuration format went through several iterations after the first release, making the man page the authoritative guide for users migrating from v1. The man page describes keyd as a system-wide daemon supporting layers, one-shot modifiers, macros, and custom layouts that persist across Wayland, X11, and TTY boundaries. ### 采用历史 keyd became popular among Linux users who wanted firmware-like keyboard behavior without flashing QMK or depending on a single desktop session. Distribution packages in Alpine, Debian, Nix, Arch, openSUSE, and Homebrew-style catalogs show adoption beyond source builds. ### 使用方式 The common first configuration maps Caps Lock to Escape when tapped and Control when held, then reloads the daemon with keyd reload. More advanced users define layers, per-keyboard IDs, application mappings, Unicode output, and home-row or one-shot modifiers. ### 为什么软件包爱好者会关心 keyd is interesting to package nerds because it packages a tiny C daemon that changes the physical typing environment for the whole machine. It is also a practical response to the Wayland transition: remapping below the display server avoids the split between X-only and Wayland-only tools. ### 时间线 - 2021: Downstream package history shows early 1.x packaging activity. - 2022: v2-era documentation told users migrating from v1 to reread the man page after config-format iterations. - 2024: Distribution bug reports and manuals show keyd being used on modern Linux kernels and Wayland desktops. - 2026: The project remained active enough for new issues and package-manager submissions around Homebrew and Linux distributions. ### Related projects - Related tools include xmodmap, xcape, interception-tools, xremap, KMonad, Kanata, and QMK firmware. keyd's distinct niche is system-wide Linux remapping with firmware-like layers but no keyboard flashing. ### 来源 - - - - - ## 安全说明 没有找到 keyd 的匹配本地密钥处理 manifest。Nucleus 软件包元数据仍在此发布，以便未来覆盖拥有稳定的软件包 URL。 ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
