Visual mode is a user-friendly alternative to the command line that offers a variety of visualization features. This allows the user to view, debug, and run the binary in a format that is easier to read. This is mostly equivalent to gdb's GEF plugin, but you directly interact with the UI rather than the UI responding to command-line arguments.
Visual mode overrides a few command-line functionalities, so it's important to discuss the Visual mode equivalents.
To enter Visual mode, use V. To quit Visual mode, use q.
There are five views in Visual mode. These are:
x: Hexadecimal view
a: Disassembly listing
d: Debugger View
v: Visual colors
c: Cursor view
The most useful view is the Debugger view. This view shows us the stack, registers, and disassembly. We can move around the binary via seeking and stepping.
Use the p command to cycle through the views. Use P to cycle through the views in reverse.
The next section will discuss how to navigate Visual Debugger Mode and how to use it to solve challenges.
