Jump button doesn't work in JDoom!

I dont understand, I set a key (Right mouse button) for jump, but when I press the button nothing happens. Can someone help me?

Well, try putting Jump on one of the keyboard keys. That's what I would do.

Jump is disabled in JDoom by default. You have to enable jumping in one of the gameplay options menus.

Wich one? I have jump button on insert key, and I also noticed that jumping doesn't work, so I checked the menus for that option, but didn't find it. Anyway jumping works sometimes, and I have the same problem with JHeretic.

Go to the console and type "allowjump 1"

Seems to work. Thanks!
