How do I make a Button activated Gui?

Does anyone know how to make it so when you press a button (not shift), a ScreenGui becomes visible? I would love some constructive feedback.

You can use UserInputService or KeyDown/KeyUp for getting keyboard input.

Localscript:

Game:GetService("UserInputService").InputBegan:connect(function(input)
	if input.KeyCode == Enum.KeyCode.KEY then
		local Gui = game.Players.LocalPlayer.PlayerGui.ScreenGui.Frame
		Gui.Visible = true
		--[[Or use
		Gui.Visible = not Gui.Visible
		for toggling visibility]]
	end
end)
