I know on X-Box there's a button for deleting your spells when you don't need them anymore, but I haven't found anything similar on the PC version yet. My spell-list is getting quite full of old crappy spells that I don't use anymore and I find that annoying.

Does anyone know of a way to delete spells from the in-game spellbook? (With or without the console)

If you search "spell delete" you should find a couple mods that will do it, but if I remember correctly, they do not actually delete the spells, they just remove them from your book. Say this is your spellbook:

Fire ball
Ice shard
Spark bolt

You decide to delete spark bolt because it has a dumb name, now this is your spellbook:

Fire ball
Ice shard

Then later you decide that the name was not so bad after all so you go to remake the spell. You will get an error that says the spell already exists even though you can not select it, use it or even see it. If that's okay by you then one of the mods should server your purpose fine.

I believe he was just looking to take the spells out of his spellbook as he said that it was full of spells he didnt need anymore. As far as I know, all you have to do is hold shift and click on the spell you dont want anymore.

Yes, it worked! Thank you! I love you!

So it was a button for doing it, I wonder why it's never mentioned in the manual.

If there is actually mods to do this then obviously many other than me didn't know you could just hold down shift
