Yesterday I have installed the latest F30 from the KDE Live media onto
my laptop, and so far it works great. The only problem I have is the
functionality of the "menu" key (sitting in between the AltGr and
right Ctrl keys on my keyboard).
Apparently, pressing that key gives a popup menu at the position of the

usecase, this behavior is useless (I use two-finger tap on the
touchpad to invoke that menu), so I want to reassign the menu key to do

capturing the keypress, the popup menu appears instead.
My google-fu failed me, since searching for anything involving "menu
key" brings up a bunch of hits describing how to assign some key
to open a menu, instead of talking about the menu key.
The only relevant suggestion I found was to reassign the keycode of the
menu key to some nonexisting regular key like F13, using xmodmap. But
this seems to be a kludge, and I'm wondering if there is a "proper" way
in Plasma to configure the behavior of the menu key.
