Google, DDG and Co. search terms are something like right+left button simulating middle button or emulate middle mouse button or remapping middle-mouse button Some threads might be way to old, other might rely on X, but I don't know if KDE override such X settings. However, consider to use a search engine and to test some hints. There is a Wiki that I found by googling for arch linux mouse buttons https://wiki.archlinux.org/title/Mouse_buttons Unfortunately it contains banners such as "The factual accuracy of this article or section is disputed." and "This article or section is out of date." Disclaimer, I did not read the Wiki, I just googled and saw the banners and I don't know if it mentions the emulation of middle mouse button at all. Also consider to sent requests to https://discuss.kde.org/ and/or https://mail.kde.org/mailman/listinfo/kde . Regards, Ralf
