Floating doodads?

[Hemske]

First of all, im tired and havent searched that well for any thread like this... But i just wanted "floating doodads" to be explained for me. I can understand that it is those doodads that looks like they are floating, or not really look like they are a part of the ground. But how do you get rid of them? Can you fix it in any way or do you have to resize/move/something else? the doodad? Im new to terraining, just started and would be great if i could get a little help with these floating doodads, beacuse my terrain is kind of full of them

Lower them into the ground a little (Ctrl + Page Down)

I don't need to click CTRL for some strange reason

I do, if I just press page down it will lower the z scaling of the model instead.
Pretty neat though.

Still, it's possible to change all those hotkeys manually.
