# LaTeX奇技淫巧

## 1. 移动符号

### 1.1 左移

• $\dashv \vdash$
$\dashv \vdash$

• $\dashv \! \vdash$
$\dashv \! \vdash$

• $\dashv \! \! \vdash$
$\dashv \! \! \vdash$

• $\dashv \! \! \! \vdash$
$\dashv \! \! \! \vdash$

• $\dashv \! \! \! \! \vdash$
$\dashv \! \! \! \! \vdash$

• $\dashv \! \! \! \! \! \vdash$
$\dashv \! \! \! \! \! \vdash$

• $\dashv \! \! \! \! \! \! \vdash$
$\dashv \! \! \! \! \! \! \vdash$

• $\dashv \! \! \! \! \! \! \! \vdash$
$\dashv \! \! \! \! \! \! \! \vdash$

### 1.2 右移

\! 相对的右移第二个符号的命令是 \,

【注】此外，除了上述方式以外，还可以使用命令\kern{npt} 来移动第二个符号的位置（pt 为 LaTeX 长度单位，也可以换成其他的）：

• $n \lt 0$：左移
• $n \gt 0$：右移

• $\dashv \kern{2pt} \vdash$
$\dashv \kern{2pt} \vdash$

• $\dashv \kern{1pt} \vdash$
$\dashv \kern{1pt} \vdash$

• $\dashv \kern{0pt} \vdash$
$\dashv \kern{0pt} \vdash$

• $\dashv \kern{-1pt} \vdash$
$\dashv \kern{-1pt} \vdash$

• $\dashv \kern{-2pt} \vdash$
$\dashv \kern{-2pt} \vdash$

• $\dashv \kern{-3pt} \vdash$
$\dashv \kern{-3pt} \vdash$

• $\dashv \kern{-4pt} \vdash$
$\dashv \kern{-4pt} \vdash$

• $\dashv \kern{-5pt} \vdash$
$\dashv \kern{-5pt} \vdash$
