In Debian Trixie - KDE System Settings the configuration for the mouse
click behavior is not working as expected. I am in detail referring to
the following settings:
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.13.0
KDE System Settings - Window Management - Windows Behavior - Window
Actions - Inactive Inner Window Actions
I observe these configurations to work correctly for the RIGHT and
MIDDLE click definitions, but for the LEFT mouse button definitions the
actually applied actions differ from the configuration. I appears as if
the list of actually applied left mouse button actions would be shifted
to the list of definitions. I'll in the following first name the option
in the Settings, and then behind a "-->" sign the actually observed
functionality:
"Activate, raise and pass click" --> activates & passes click
"Activate and pass click" --> activates
"Activate" --> activates and raises
"Activate and raise" --> passes left click (no Activate and no Raise)
"Activate, pass click and raise on release" --> activates & raises &
passes click
If you are trying to get single left click instead of double click then you need to configure: System Settings > Workspace > General Behavior. Scroll down to the clicking files or folders options and select "Opens Them"
