Ability to use a Global Hotkey to Activate Window

[excalq]

I'm aiming to replicate a functionality available with Yakuake, Guake, and iTerm2 on MacOS: A global keyboard shortcut "hotkey" to activate the single window session of Limux that I've opened. Fwiw, I'm a KDE Plasma 6 user.

I've attempted to use KDE's global shortcuts to launch the application, however this always open an additional window, not the singleton that I would prefer to keep. I've not yet tried this in other desktop environments.

In summary, either having a way to enforce singleton behavior, or better yet, provide an argument/mechanism for opening the application with a currently open window, where one exists would be ideal. This could either use the desktop environment's shortcuts tooling, or be integrated into Limux's own shortcuts.

Valid enhancement. Current multiple-window behavior is intentional: commit 0c615e2 made the GTK application non-unique, so launching Limux creates another process/window. PR #54 separately prevents later processes from stealing the first process control socket.

Keeping this open for an explicit activate-existing contract suitable for desktop global shortcuts. A focused implementation should expose a CLI command such as limux activate over the control socket, present/focus the owning window without creating a workspace, define behavior when no instance exists, and document KDE/GNOME shortcut setup. This should preserve current multi-instance support rather than silently changing no-argument launch semantics.
