# 可视化模式

可视化模式是radare2中一个对用户比较友好的命令行界面。其具有基本的导航功能，可以用光标选择字节，并提供了一系列的快捷键简化调试时的操作。 使用`V`命令可进入该模式，在该模式中按下`q`可退回到原本的命令行界面中。

## 导航

支持使用HJKL键或方向键与PageUp/PageDown进行导航，也支持通常的Home/End键。如vim一样，可以在前面加上数字将动作重复多次，比如说`5j`将会下移5行，`2l`则会右移2个字符宽度。

## 切换输出模式

可以在可视化模式中循环地切换"输出模式"，默认的循环顺序为:

↻ **Hexdump panel** -> **Disassembly panel** → **Debugger panel** → **Hexadecimal words dump panel** → **Hex-less hexdump panel** → **Op analysis color map panel** → **Annotated hexdump panel** ↺.

另外值得一提的是，界面顶部包含了当前所使用的输出命令，例如反汇编界面中显示的是：

```
[0x00404890 16% 120 /bin/ls]> pd $r @ entry0
```

## 获取帮助
