What is the correct setting to add a second button for jumping in the Input Manager?

In Unity's Input Manager, the correct setting to add a second button for jumping is to use the Alt Positive Button option. This setting allows developers to define an additional key or button that can trigger the same action as the primary input.

By assigning a second button for the jump action, you provide flexibility for players who may prefer or require different controls, such as players using various controller layouts or custom keyboard setups. In scenarios where both a primary and an alternate input for jumping are desired, this setting effectively facilitates dual input detection without the need to create a completely separate input axis.

The other options don't serve the same purpose: Positive Button refers to the main input button, Jump Button generally signifies the button's name, and Secondary Jump Key is not a recognized setting in the Input Manager. Therefore, utilizing the Alt Positive Button is the most appropriate choice to achieve the desired functionality for a second jump button.
