Had a problem with iTunes today when I ran out of disk space while downloading some new podcasts. To quickly get some space, I deleted a hand full of podcasts to make room for new ones. After I recovered some space elsewhere on the drive, I returned to iTunes to restore a handful of podcasts I didn't really want to delete.

Problem is, once I deleted a podcast, there appeared to be no way to restore it. Using the "refresh" podcast option did not return these items to the list, nor are there any options in the menus to restore the deleted podcasts.

After poking around the web, I discovered that on a Mac, clicking on the triangle next to the podcast name while holding the "option" key, will return all the deleted episodes to the podcast's list. Not having a Mac, I tried the Ctl, Alt, and shift keys while clicking the triangle.

Eureka! "Shift" clicking the triangle restored the missing podcasts to the list allowing me to download them again. I also discovered "Control" clicking the triangle will open or collapse all podcasts at once.

I can understand why a deleted podcast is removed from the play list as normally once I delete a podcast, I am done with it. However, I would have thought it would have been documented somewhere how to restore these files.
