lol are you blind???
q: basic structures menu
w: advanced structures menu
e: medpack, ammopack menu
r: equipment menu
once in a menu, you use a-s-d-f-g -z-x-c-v for the what to drop
for example...need medpack, press e and then
a= medpack s = ammopack d = cataclyst pack
its all in the left side of the keyboard, and if you have any skills at all/ you are not 80 years old, you should memorize them quite quickly
There are also some more advanced binds....in the console you can write bind x .....and then something that I cant remember......and then that button will select the closest obs/TF whatever the bind is for....and I really dont wanna waste my time looking for it

but I dont know how to drop dual medpacks
