I use https://github.com/houmain/keymapper to achieve the same thing, Meta + W: open or switch through existing Firefox windows, Meta + Z: open or switch through existing Terminal Windows, etc.
It works on Wayland from my understanding, but I'm using X11 as my daily driver.

Project mention: Show HN: Automat – A New (Game) Automation Utility | news.ycombinator.com | 2026-01-30
I’m happy to say that a new open-source game automation utility that I’ve been working on for the past 2 years is now coming to Steam!
It has a website at https://automat.org/. That website might be a little hard to parse though - so here are are some links:
you can check it out on video here: https://www.youtube.com/watch?v=BBT9XO61B5I (I usually do a short intro on every development livestream)
GitHub is here: https://github.com/mafik/automat
an article about Automat: https://automat.org/live2025 (if you have any questions - check this out first!)
and the Steam page is here: https://store.steampowered.com/app/4122050/Automat/
While Steam version is still in “coming soon” mode, you can grab a release from GitHub. Please note that even though it's free on GitHub, Steam Wishlists are still important for visibility - this is what drives the Steam algorithm! The easiest way to help out is to hit the wishlist button :P
One word of warning - it doesn’t play well with Wayland (it’s fairly hard to interop with other apps on Wayland) - but I’m optimistic about this bit in the near future...
And finally - don't be fooled by it's seemingly game-oriented focus. At it's core it's a visual programming environment!
