Easy: under the list of smilies (given you don't use the QUICK REPLY box, which was shrunk in the washing, too !) next to the reply-box ("Go Advanced") there is a little link to more... . Click it and a new page opens with all these little ones.
I know some of their "names" by heart meanwhile and can type them in.

Though Anty and I also like to IMPORT smilies from elsewhere, sometimes, heehee.
