Bind mouse click on key including mouseclick hold function

For health reasons, i mapped the mouse buttons on keys on keypad. This helps me, but I have solved the bindings via xdotool in KDE Custom shortcuts. With e.g. xdotool click 1 you can simulate simple mouse clicks, but I would also like to drag a window when the mouse button is permanently pressed. Under windows this was possible with AutoHotKey. Is there an option to set this up in linux as well? I use Kubuntu 20.04 and KDE 5.
