Game keeps crashing (item renderer?)

[WonderPup]

I was wondering if anyone knew a fix to this issue. Basically, I (ingeniously) made it where if I left-click, the item renderer pops up.

To try and resolve this, I tried to go back into the options >> controls >> etc in-game. Of course, this couldn't happen, because item renderer would break whatever I was trying to do when I would left-click. It then crashed my game.

I logged out at the behest of a friend to attempt to change the item renderer control through the main log in screen. This also crashes my game.

The crashes may be unrelated to item renderer. I don't know. I'm not computer savvy at all. I've attached the last crash report.

The EXACT same thing happened to me just now, I don't know how to fix it though :/

That's easy, manually edit the options.txt in mindcraft directory

Here's one I prepared earlier, I bound the errant function to the F12 key.

Can you please elaborate on how to change the options.txt thing?

Edit:Nevermind I just clicked on the file you posted and copy and pasted it into mine. THANK YOU SO MUCH. Freman is the best.
