TeXstudio：过多的自动完成功能

Question

当我在数学环境中工作时，我想输入类似 的内容\sec^2x，只要我在^之后输入\sec，它就会自动完成\sec。\section或者当我在tikzpicture环境中工作时，我想输入，只要我输入 ，rotate = 90它就会自动完成rotate =。有没有办法停止特定命令的自动完成？我不想放弃在我工作的任何环境中自动输入。rotate around x==\end{}

编辑：我正在使用 TeXstudio 版本 4.7.2。以下是一些示例，我正在写出一些毕达哥拉斯恒等式：

\[\tan^2\theta=\sec^2\theta-1\]

或者我正在绘制一个图表并希望旋转一些节点：

\begin{tikzpicture}
    \draw (0,0) -- (0,3) -- (3,0) -- (0,0);
    \node[anchor = south, rotate = 90] at (0,1.5) {Silo};
    \node[anchor = south, rotate = -90] at (0,1.5) {50 feet};
    \node[anchor = north] at (1.5,0) {Shadow};
    \node[anchor = south] at (1.5,0) {$L$};
    \node[anchor = south east, xshift = -.4cm] at (3,0) {$\theta$};
\end{tikzpicture}

我希望这能澄清一些事情。

    Pythagorean Identities:
    \[\sin^2\theta=1-\cos^2\theta\hspace{1in}\tan^2\theta=\sec^2\theta-1\hspace{1in}1=\csc^2\theta-\cot^2\theta\]
    \begin{Ex}
        Picture first.
        \begin{center}
            \begin{tikzpicture}
                \draw (0,0) -- (0,3) -- (3,0) -- (0,0);
                \node[anchor = south, rotate = 90] at (0,1.5) {Silo};
                \node[anchor = south, rotate = -90] at (0,1.5) {50 feet};
                \node[anchor = north] at (1.5,0) {Shadow};
                \node[anchor = south] at (1.5,0) {$L$};
                \node[anchor = south east, xshift = -.4cm] at (3,0) {$\theta$};
            \end{tikzpicture}
        \end{center}
        Now we have to make a function of $\theta$ that finds $L$.  Well we're dealing with the opposite and adjacent, so we use tangent.
        \begin{align*}
            \tan\theta &= \dfrac{50}{L}\\
            L &= \dfrac{50}{\tan\theta} = L(\theta)
        \end{align*}
    Part 1 done.  We have the function.  Now we just substitute the values into the function.  For $10\degs$, $L(10) \approx 283.56$ feet.  For $30\degs$, $L(30)\approx 86.60$ feet.  For $50\degs$, $L(50)\approx 41.96$ feet.
