I have an hp laptop and the shift click isn't working(sims 4)

@sasamiraaa  Just to be thorough:  When you enter testingcheats true , do you see the message that cheats are enabled?  If you use a second cheat that requires testingcheats to be active first, for example money x (with x being the amount), does it work?

Does this shift key you're using work outside of Sims 4?  Have you tried using the other shift key instead?  Does shift-clicking on the ground or an object bring up the menu you'd expect when cheats are enabled?  For example, shift-clicking on the ground should offer "teleport me here," and shift-clicking on a sink should offer "make clean" or "make dirty."
