PageUp / PageDown not being detected by UserInputService

[rogeriodec_games]

Reproduction Steps

Run this in a LocalScript and press PageUp and PageDown:

local UserInputService 	= game:GetService("UserInputService")
UserInputService.InputBegan:Connect(function(Input,GPE)
	print ("InputBegan", Input.KeyCode)	
end)

UserInputService.InputChanged:Connect(function(Input, GPE)
	print ("InputChanged", Input.KeyCode)	
end)

-- InputEnded
UserInputService.InputEnded:Connect(function(Input)
	print ("InputEnded", Input.KeyCode)	
end)

Expected Behavior
UserInputService might recognize both keys, since they are listed on KeyCode | Roblox Creator Documentation

Actual Behavior
The camera view is moving up and down

Can’t reproduce. Have you considered that one of your scripts might be sinking input on these keys?

I don’t know what can be creating this problem in my game.
I’m trying with someone else here:

PageUp / PageDown not being detected by UserInputService.InputBegan

There’s definitely something weird about my game because running the example above on a new BasePlate, will recognize these keys. The strange thing is this: in my game, it will only recognize PgUp and PgDown if I keep pressing the Ctrl key… UserInputService.InputBegan:Connect(function(Input,GPE) print("Input,GPE: ", Input,GPE, Input.KeyCode) Input,GPE: InputObject false Enum.KeyCode.LeftControl Input,GPE: InputObject false Enum.KeyCode.PageUp Input,GPE: InputObject false Enum.KeyCode.…
