使用Alt =是快速在Excel中求和的快捷方式，能顯著提升效率。具體操作如下：1. 將光標(biāo)置于需求和的列下方或行右側(cè)；2. 按下Alt =，Excel會自動插入SUM公式；3. 若數(shù)據(jù)連續(xù)，可直接完成求和，若有空白則僅對首個空白前的數(shù)據(jù)求和；4. 可先選多個單元格再使用快捷鍵實現(xiàn)多行列同時求和；5. 需更精確控制時，可結(jié)合方向鍵調(diào)整范圍；6. 若數(shù)據(jù)含隱藏行，可用=SUBTOTAL(109, 范圍)僅對可見單元格求和，且可自定義快捷鍵以提高效率。

If you're looking to add numbers quickly in Excel without reaching for the mouse, there's a shortcut for sum that can save you serious time. It’s not just about typing faster—it’s about keeping your hands on the keyboard and maintaining your flow. Here’s how to use it effectively.

Use Alt = to AutoSum a Column or Row

This is the go-to shortcut for summing a range of numbers in a column or row. Place your cursor below a column of numbers (or to the right of a row), press Alt =, and Excel will automatically insert a SUM formula for you.

• Works best when your data is continuous (no blank cells in the middle)
• If there's a gap in the data, it sums only up to the first empty cell
• Saves time over manually typing =SUM()
• You can also select multiple cells before using the shortcut to sum multiple rows or columns at once

It's especially handy when you're dealing with large tables and want to avoid scrolling or dragging with the mouse.

Combine with Arrow Keys for More Control

If your data isn’t perfectly aligned or you want more control over what gets summed, you can combine the shortcut with navigation keys:

1. Navigate to the cell where you want the sum to appear
2. Press Alt =
3. Then use arrow keys or type the range manually if needed
4. Hit Enter to complete the formula

This method works well when you're deep into data entry and don't want to break your rhythm by switching to the mouse.

Watch Out for Hidden Rows or Filters

One thing to keep in mind: if your data has hidden rows or filters applied, Alt = will still sum all values—including those visually hidden. If you want to sum only visible (filtered) cells, you’ll need a different approach:

• Use =SUBTOTAL(109, range) instead of regular SUM
• There's no built-in shortcut for SUBTOTAL, but you can create a custom keyboard shortcut if you use it often

That said, for most day-to-day tasks, Alt = is fast, reliable, and easy to remember.

基本上就這些。掌握這個小技巧，能在日常處理表格時省下不少時間，尤其是當(dāng)你習(xí)慣鍵盤操作之后，效率提升會更明顯。
