I'm using KDE on Fedora and I have a decent grasp of the command line. What I want to achieve is a global and persistent remap of the middle click to act as a right click, mainly as a workaround for another issue I'm experiencing. I'm not concerned with keeping the middle click functionality.
From what I've gathered, Libinput seems like the right choice for KDE, but I'm not seeing any utilities for remapping in the documentation. Should I just go ahead and use xinput even though the console warns me against it? I've also tried the Input Remapper GUI but it doesn't recognize middle click inputs, making it tough to select manually.
To add, I'm looking at this remapping not just for the touchpad but also to find out if it can help me globally remap devices like my stylus pen. The KDE settings aren't allowing me to remap the pen ([bug report here](https://bugs.kde.org/show_bug.cgi?id=512572)), so I'm really pushing for a solution.

I’d suggest giving Input Remapper a shot. It might not have worked for your middle click directly, but it could still be worth a try for other configurations.
Are you worried about compatibility with Wayland? It can affect how KDE looks and performs, but if you're mainly focused on getting your middle click functionality sorted for the touchpad, you might be in the clear.
Just know that I'm also dealing with a similar issue with a stylus pen. Trying to map it properly has been a headache, and I've resorted to global remaps to tackle it until better support arrives.
If you're only trying to remap the touchpad, you might want to check out the Synaptics drivers, as they can handle some remapping options. You can find helpful guidance on the Arch Linux wiki regarding Libinput and tapping remapping. Here's a link to what I found: [Arch Wiki on Libinput](https://wiki.archlinux.org/title/Libinput#Tapping_button_re-mapping). Just keep in mind that if you do go for xinput, be cautious with the warnings you’ll see—it might work but there's a chance things may get tricky.
I think what they mean is that Synaptics drivers can handle certain tasks well. If you’re struggling to find their drivers, just remember that they aren’t a brand per se, but more of a driver type for handling touchpad functionalities.
Yeah, Wayland can get complicated, especially if you're not familiar with it. For your specific use case, if changing mouse settings doesn’t affect how your GUI looks, then you should be fine.
