Cheers, can someone help me out for a sec?

Soo im new to the Unreal engine and i was trying to follow the in program tutorials to the terrain editor.
however it kinda threw me a curve ball at this point

i cant see any magnifying glass, or a plus sign =)

You have to apply a material to your Landscape so the Target Layers which have the plus signs show up. This is mentioned in the steps previous to the one shown in your screenshot.
