The console will then give you every possible ID with the word you put in the quotes. Also, know that you can use Page Up/Down on your keyboard to scroll the console.
So, say I wanted grand soul gems. I would type:
help "grand soul gem" 0
The console will return to me the item ID's for an empty grand soul gem, and one with a grand soul in it. (Note: It doesn't tell you which is which, but generally, the more generic, or unfilled in a soul gems case, are listed first.)
There, now you never have to go online to look for item ID's again!
