Press 1 on top of Q,Under F1
Im using a window 10 computer and I didnt buy spray yet, the lube bottle wouldnt show though even though I pressed 123 the only time I got my hands on spray was on the tutorial edit: nevermind items such as stair and lube bottle does not show in the tutorial or actual game I tried to click on it multiple times it doesn let me equip the lube bottle so I can trade it for the spray but it did let me equip the stairs for some reason
