I just use something like Super+Space.
That's a good solution, and easy to remember. CrunchBang uses this for the Openbox menu. It also has all the keyboard shortcuts including this one listed on the desktop, using Conky. (This, along with a good README and a welcome script, makes life easier for someone new to the distro, and these should all be more common in Linux distros IMO.)
