loading sketches to forum

loading code: I seem to have forgotten how to up load sketches from my computer to the forum.
I click on the edit button and then click copy to forum but cannot find the copy anywhere.

It's copy for forum, not copy to forum.

You mark the code, you select Copy for Forum (or ctrl+shift+c). You create a forum post and in it you do Paste (or ctrl+v). You get your code there with beautiful code tags.
