Eagle PCB Add - drop button - what does it do

[Harvey]

Hi Eagle users,
On the ADD dialog there is a "drop" button. What does it do? Where is
it documented?
(I have the free version)

Okay, I figured it out (reading other posts) it drops the current
library (the hilighted one). And you can get it back by going to the
Control Panel Libraries and click the dot to make it green again. Whew!
I was worried when my whole "rlc" library disappeared.
