Rust has posted version 1.06 of Q3Build, the first front end compiler for Q3Map. I saw there that QERadiant.com has posted a tutorial on the new Curves menu for Q3Radiant. Speaking of QER, the first of RiceBug's On-Line Q3A Tutorials, with an introduction to the Q3Radiant editor. Finally, Rust has also posted a downloadable list of keys for the Q3Radiant editor.
