The visual mode is a more user-friendly interface alternative to radare2's command-line prompt. It allows easy navigation, has a cursor mode for selecting bytes, and offers numerous key bindings to simplify debugger use.
To enter visual mode, use
V command. To exit from it back to command line, press
Navigation can be done using HJKL or arrow keys and PgUp/PgDown keys. It also understands usual Home/End keys.
Like in Vim the movements can be repeated by preceding the navigation key with the number, for
5j will move down for 5 lines, or
2l will move 2 characters right.
The Visual mode uses "print modes" which are basically different panel that you can rotate. By default those are:
↻ Hexdump panel -> Disassembly panel → Debugger panel → Hexadecimal words dump panel → Hex-less hexdump panel → Op analysis color map panel → Annotated hexdump panel ↺.
Notice that the top of the panel contains the command which is used, for example for the disassembly panel:
[0x00404890 16% 120 /bin/ls]> pd $r @ entry0
