Help me please

@$$anonymous$$123122 : what the... Why a downvote? You zoom with the scrollwheel in the first place. We don't know that you don't have a mouse because everybody has one. You should have said that in your actual question ins$$anonymous$$d of downvoting. It was missing information from your side.

You can also zoom by holding down ALT and the right-mouse-button (don't say your laptop doesn't have a touchpad. If that's the case you should stop developing with Unity or buy a new laptop).

You should ask specific detailed questions. A single 13-word-sentence if not much information. Also tags should also describe your problem "unity" and "help" is totally useless.
