Refer to this
page for a list of cheat codes. For the giveitem cheat, enter the name of the item. For a blue lightsaber, for example, you enter "giveitem g_w_lghtsbr01". If you don't want to memorize a list of item names, use KSE instead to add items to your inventory.
Also, don't create multiple threads all discussing the same or similar topics. The moderators frown upon this. Simply continue the discussion within the same thread if it is relevant.
