From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've got three hard problems preventing me from using Wayland (sway/wlroots) right now:
There's a portal for Global Shortcuts: https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.GlobalShortcuts.html
KDE and Hyprland already implement it, and COSMIC seems likely to
On the app side, if we can get the major toolkits to adopt it, then hopefully that covers most actively-maintained apps (but it's unlikely to cover legacy apps): https://github.com/electron/electron/issues/38288
If I can get the portal to just forward every keypress (or a configurable subset) to an xwayland window, that'd work for me. (I am aware of the security implications.)
As far as I know xwayland in plasma/kde already does that. However as it's KDE, it is most likely configurable and might not be enabled by default :P
I'm not an expert, but my understanding of the Global Shortcuts portal is that it's very much designed for the push-to-talk use case where an app is not focused but still receives button events for exactly the keys its interested in and no other keys: I think this would cause problems if an app requested every key (e.g. if the request was approved then no keys would work in every other app)
It'll be interesting to see how the remaining compatibility/accessibility issues are tackled, either in portals or in wayland protocols
Yeah and that's great but my point is that I don't see an obvious way to use it for that in its current implementation. I'm sure you could build it but it's simply not built yet.
