How to put items in shoping cart?

Hi, i play cataclysm for 3 hours and i still do not know how to put items into vehicles (cars, shoping carts). Anyone can tell me how to do this?

"D"rop items.

Capital D lets you drop into adjacent tiles, just drop them on the part of the vehicle you want it on.

You can also use advanced interface by pressing “/” (without quotes). Then press “d” in one pane to select the cart (must be grabbed), and in the other pane press “i” for inventory or “a” for all adjacent tiles (minus the cart, if selected in the other panel).

Yeap, just stand over the cart and "d"rop the items in. You can also check the handy dandy wiki here :http://www.wiki.cataclysmdda.com/index.php?title=Main_Page or press “?” ingame to access the ingame information menu for any future questions you may have.
