Multiple files into CD-ROM

Centos 4.2 current, Gnome and KDE. Evidently, support for Nero is done through this forum. I have downloaded the PDF quick start guide (there being no more complete user’s manual) and have read it. Suppose one has some directory on a filesystem that contains N files (file0, file1, etc.). At present in Nero, it appears that has to click on each file, drag it to the writing sub-window, and iterate. There appears to be no way to “range select” from the N files some M items (because all N combined may exceed the CD-ROM capacity). Am I missing something? I have a three-button pointing device, but no scrolling wheel as with more current pointing devices.

Have you tried shift-click / ctrl-click ? This is acting like under Windows
