There was a way of obtaining all of the potions by pressing a key (which I have forgotten) and then the numbers 1-(I think) 7 in sequence. As this was done, all of the potions would appear under the screen. Please help, and jog my ancient memory as to which key it was. I have tried ALT, Ctrl, Shift, Enter, all the the Function keys, to no avail. Is there somebody out there who knows the secret?

Re potion cheat : I found it. Press the "P" key and 1, which gives you the blue potion, then continue, one at a time, and you will have all of the potions.
