# Function only Mode (/docs/function-only-mode)





By default, the debugger operates only at the function level.

## Use the debugger [#use-the-debugger]

The debugger has standard definitions for:

* **Next:** goes to the next function call (depth first search order)
* **Previous:** goes back to the previous function call
* **Step Over:** goes to the next function call (DO NOT go to nested calls)
* **Step Up:** goes up one level

## Inspect the variables [#inspect-the-variables]

Under this mode, users can visualize **Inputs**, **Return Value** and **Gas info**.
