I don't recommend this one with kde desktop Not sure how it is with big screen.
If you are looking to clone TV remote IR buttons there is this one. The orange buttons can clone TV remote buttons. https://www.amazon.com/Rii-Wireless-Keyboard-Touchpad-Controller/dp/B0C5LFLL3G/ref=mp_s_a_1_1_pp?crid=247JUEQKDFAAL&dib=eyJ2IjoiMSJ9.J1g9QtAF8xB3mG5ZS6etrWUR8cxrIbmY-Oit0UosNDdx9GOe4HOH-SC-IgSIymfthR7fZA7_WdoiGNPvKqQzpXxYvOVi4cy7zqdiaK3qTTq8s5T7F8mWjjIICmOJFabGJAaYknW4Yo82sn18O3n_Vb2D-E0LQYl7qgUqoUcAJd07BoTIgZTmgvqsqWl_3clD0sbzKhjFKfDdixiRLuBCSw.5mMB6rANHKQtxt1qbEeHzMvBxR3Rep5-BBOJFQlMZZs&dib_tag=se&keywords=rii&qid=1725324362&sprefix=rii%2Caps%2C127&sr=8-1
If you are going to use a PC desktop (kde is great) I recommend getting one with the scroll wheel.
So many races employed...
