Let me try and help you out then.
You must be registered to see attachments
If you press "Reply", the post you're replying to will be inserted into the message box.
But if you press the "Quote" button, it will be stored, and you will be able to find it here.
"Insert Quotes", when pressed this will popup.
You can rearrenge if you have multiple, by dragging the "button" with three lines.
When done, just press "Quote Messages" and they will be in the message box, ready for you to reply to!
Now, the next step is the "edit" button...
But Slum, nobody asked for you help...
Nope but had nothing better to do anyways.
