渲染。\u003C\u002Fp>\n\u003Cp>以前的解决方案要么很麻烦（在本地装 LaTeX 然后截图）、要么效果差（直接贴代码让对方看 \u003Ccode>\\frac{-b\\pm\\sqrt{b^2-4ac}}{2a}\u003C\u002Fcode>）。MeTool 的 LaTeX 公式编辑器专门解决这个环节：输入 LaTeX 公式，实时预览渲染效果，一键导出为高清 PNG 图片或矢量 SVG，再粘进任意平台。\u003C\u002Fp>\n\u003Cp>整个过程在浏览器里完成，不需要安装任何软件，公式内容不离开你的设备。\u003C\u002Fp>\n\u003Ch2>如何用好快捷符号面板——不用死记 LaTeX 命令\u003C\u002Fh2>\n\u003Cp>LaTeX 语法的学习曲线陡峭的原因之一，是常用命令太多且不直观：希腊字母要写 \u003Ccode>\\alpha\u003C\u002Fcode>、分数要写 \u003Ccode>\\frac{}{}\u003C\u002Fcode>、积分要写 \u003Ccode>\\int_{a}^{b}\u003C\u002Fcode>……对于偶尔写写公式的用户，记这些命令效率很低。\u003C\u002Fp>\n\u003Cp>编辑器右侧的符号面板提供了另一个入口：\u003C\u002Fp>\n\u003Cul>\n\u003Cli>\u003Cstrong>快捷符号\u003C\u002Fstrong> Tab：希腊字母（α β γ Δ Σ…）、运算符（± × ÷ ≤ ≥ ≠ ∈ ∇ ∂…）、上下标标注（x² xₙ x̄ x̂ ẋ）——点一下，命令直接插入到光标位置。\u003C\u002Fli>\n\u003Cli>\u003Cstrong>公式模板\u003C\u002Fstrong> Tab：分数 \u003Ccode>\\frac{}{}\u003C\u002Fcode>、根号

\u003Ccode>\\int_{a}^{b}\u003C\u002Fcode>、矩阵、行列式、分段函数、对齐环境——插入后光标自动跳到第一个需要填写的参数位置，不用手动定位。\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Cp>移动端操作模式：默认显示代码编辑区，点开符号面板选择后自动跳回代码区——两个区域都能在全屏宽度下操作，不用双手切换。\u003C\u002Fp>\n\u003Ch2>导出格式怎么选：PNG、SVG、还是复制

小。\u003C\u002Fli>\n\u003Cli>\u003Cstrong>复制 LaTeX 源码\u003C\u002Fstrong>：适合目标平台原生支持 LaTeX 的情况——Notion、Obsidian、Jupyter Notebook、Typora、GitHub README（行内 \u003Ccode>$...$\u003C\u002Fcode>，块级 \u003Ccode>$$...$$\u003C\u002Fcode>）。点击「$…$」按钮可自动在源码两端加上美元符号分隔符。\u003C\u002Fli>\n\u003Cli>\u003Cstrong>复制 SVG 代码\u003C\u002Fstrong>：直接将 SVG 标签代码复制到剪贴板，可粘进 HTML 文件或支持 SVG
