I made thisa small shell script + systemd unit file I call https://github.com/mathportillo/wayland-mouse-mapper.
it can easily be altered to trigger mouse click events instead of other key events
excerpt mathportillo/wayland-mouse-mapper
A small script for mapping mouse buttons to keystrokes on Wayland.
I made for myself to use my mouse extra buttons for useful stuff. It's tested and works with Logitech MX Master 2S on Fedora 27 using Gnome, and works it on my old Logitech Performance MX too. It probably works on any Wayland and Any Logitech mouse (or any mouse if you edit mappings) because no other method (xdotools, xbindkeys, etc.) seemed to work.
It works by reading from libinput debug-events and triggering key events using evemu depending on the recognized button from the recognized device.
Buttons
These are just the default settings, you can customize them at the start of the mousemapper.sh script.
- Forward: Move to workspace above (Super+Page up)
- Back: Move to workspace below (Super+Page down)
