I would like to know how to zoom with OptiFine mod for minecraft 1.2.5. I have been on the controls in the options and changed the key to z, but when I pressed it, it doesn't zoom. So, I changed it back to the default key, Left Control, but that doesn't work either. Can anyone help me? I know OptiFine is installed because of the extra options that it adds.
I'm going to assume it's a problem with your keyboard. I've switched Zoom-In with "x" for me, and it works fine.
Try cleaning out your keyboard, and if it's still problematic, then try uninstalling and reinstalling Optifine.
If it's a problem with a keyboard, try opening a word document and testing all the keys you think are problematic. I once rented an acer laptop from my school, and the keyboard proved to be busted. Most of the keys, including "E", "Q", "Ctrl", "Delete", "Enter", and "S".
As you can see, that just wouldn't work out well. The IT guy had to take out the keyboard and reattach it. That only made it worse. Then he salvaged another working keyboard from another broken computer and switched them. That fixxed it.
Actually, I too share the same problem as AbhiKap.
And I know Optifine is installed correctly (also, I have used multiple versions of Optifine, none have worked), and I am certain that my keyboard is in perfect condition.
The zoom feature works perfectly in multiplayer for me, however no matter what keys I assign to the "Zoom" function in single player, it is to no avail.
I have even scoured the configuration files for Optifine for an answer.
Still looking for a way to resolve this, but if I find it I will report back.
