要快速應(yīng)用上標(biāo)格式，可使用Ctrl Shift =（Windows）或Command Shift =（Mac）。此快捷方式適用于Microsoft Word、Google Docs等多數(shù)文本編輯器。1. 使用時先選中字符或在字符后放置光標(biāo)；2. 按下對應(yīng)組合鍵即可觸發(fā)上標(biāo)格式；3. 若快捷鍵無效可嘗試再次按下以切換狀態(tài)、檢查程序設(shè)置或使用右鍵菜單中的上標(biāo)選項；4. 注意勿與用于下標(biāo)的Ctrl =（Windows）或Command =（Mac）混淆。

To quickly apply superscript formatting in most word processors or text editors, you can use the keyboard shortcut Ctrl Shift = (on Windows) or Command Shift = (on Mac). This shortcut works in programs like Microsoft Word, Google Docs, and many other text editing environments.

How to Use the Superscript Shortcut

The main way to trigger superscript is by using the shortcut keys. Here’s how it typically works:

• On Windows: Hold down Ctrl, then press Shift and = at the same time.
• On Mac: Hold down Command, then press Shift and = together.

You can either select the character or number you want to format first, or place your cursor immediately after the character and apply the formatting. It’s especially useful for things like exponents in math equations or formatting footnotes.

Common Programs That Support the Shortcut

Most modern writing and editing software supports this standard shortcut:

• Microsoft Word: Works reliably once you highlight the text.
• Google Docs: Also supports the same shortcut across browsers.
• LibreOffice: Follows the same logic as Word.
• Some email clients and note-taking apps: May vary, but many follow the same pattern.

If you're working in a less common app or website, it might not support the shortcut — in that case, look for a superscript button (often labeled with an “x2” icon) or check the menu options under "Format" or "Text."

What If the Shortcut Doesn’t Work?

Sometimes, the shortcut might not work due to conflicting program settings or keyboard layout issues. In those cases:

• Try pressing the keys again to toggle off superscript if it was already on.
• Check whether your application has changed the default shortcut in its preferences.
• Make sure you’re not in a special mode like equation editor or table cell that might block formatting.
• As a fallback, right-click the selected text and choose Superscript from the context menu.

It's also possible that some web-based tools or mobile apps don’t support the same shortcuts — so keep that in mind when switching platforms.

Superscript vs Subscript: Don’t Mix Them Up

There’s also a similar shortcut for subscript, which moves text down instead of up. The key combo for subscript is usually Ctrl = (Windows) or Command = (Mac). Be careful not to accidentally toggle between the two — they often share related shortcuts and can be easy to mix up if you're not paying attention.

基本上就這些。
