Opening the document and making your first edit

To modify a Word document, open the file in Microsoft Word, then click anywhere in the text where you want to make a change. The cursor — a blinking line — appears at that spot. You can now type new text, delete existing text by pressing Backspace or Delete, or select a block of text and replace it all at once.

If the document is already open on your screen, you can start editing right away. If you need to open it first, find the file on your computer, double-click it, and Word will launch. On a Mac, you may need to wait a few seconds for Word to fully load before you can begin typing.

Word saves your changes automatically if you have autosave turned on — you can check this by looking at the top of the window. If autosave is off, you must save manually by pressing Ctrl+S (Windows) or Command+S (Mac), or by clicking File and then Save.

Key Takeaways

  • Click in the document to position your cursor, then type, delete, or select and replace text using your keyboard.
  • Use Find and Replace (Ctrl+H on Windows, Command+H on Mac) to change the same word or phrase throughout the entire document at once.
  • Track Changes lets you see who made what edits and when, and lets others review your changes before they become permanent.
  • Formatting changes like bold, italics, font size, and color are applied through the Home tab or by right-clicking selected text.
  • Always save your document after making changes, either manually or by relying on autosave if it is enabled.

Selecting and replacing text in bulk

When you need to change the same word or phrase many times, use Find and Replace instead of editing each instance by hand. Press Ctrl+H on Windows or Command+H on Mac. A dialog box opens with two fields: "Find what" and "Replace with."

Type the word or phrase you want to find in the first field. Type what you want it to become in the second field. Then click "Replace All" to change every instance at once, or click "Replace" one at a time if you want to review each change before it happens. Word tells you how many replacements it made when it finishes.

Be careful with Replace All on short words — searching for "the" and replacing it with "that" will change "the" inside other words too, like turning "weather" into "weathat." If you are unsure, use Replace one at a time the first time you try it.

Tracking changes so others can review edits

If you are working with other people on the same document, turn on Track Changes so everyone can see what you modified. Click the Review tab at the top of the window, then click Track Changes. A toggle switch appears — click it to turn tracking on. The switch will be highlighted or show "on" when it is active.

From that moment forward, every edit you make appears in a different color with a line through deleted text and underlining for new text. Word also marks who made the change and when. Other people can see these marks and decide whether to accept or reject each one.

To accept or reject changes, stay on the Review tab. You will see buttons for "Accept" and "Reject" next to each change. Click one or the other, and Word moves to the next change. When all changes are reviewed, click "Accept All" or "Reject All" if you want to handle the rest in one action. Once accepted, the changes become permanent and the colored marks disappear.

Changing fonts, colors, and text formatting

To make text bold, italic, or underlined, first select the text by clicking and dragging across it, or by double-clicking a single word. Then press Ctrl+B for bold, Ctrl+I for italic, or Ctrl+U for underline on Windows. On a Mac, use Command+B, Command+I, or Command+U.

To change the font, font size, or text color, select the text first. Then use the Home tab at the top of the window. You will see a dropdown menu showing the current font name — click it to choose a different one. Next to it is a number showing the current font size — click that to make text larger or smaller. The "A" with a colored bar underneath is for text color — click the small arrow next to it to pick a new color.

You can also right-click selected text to open a menu with formatting options. This is often faster than navigating the ribbon at the top, especially if you only need to change one thing.

Adding, deleting, and moving entire sections

To add a new paragraph, click at the end of the line where you want the break and press Enter. A new line appears below, and your cursor moves there. To delete a whole paragraph, click anywhere in it and press Ctrl+Shift+X on Windows, or select the entire paragraph by triple-clicking it and then pressing Delete.

To move a section of text to a different place in the document, select it by clicking and dragging, then press Ctrl+X on Windows or Command+X on Mac to cut it. Click where you want it to go and press Ctrl+V (Windows) or Command+V (Mac) to paste it there. The text disappears from the old location and appears in the new one.

If you cut something and then change your mind, press Ctrl+Z (Windows) or Command+Z (Mac) to undo the last action. You can undo multiple times to go back several steps. Redo — Ctrl+Y on Windows or Command+Y on Mac — brings back an action you just undid.

Using comments to leave notes without changing the text

Comments let you leave feedback or questions about a document without actually editing the words. Select the text you want to comment on, then click the Review tab and click "New Comment." A box appears where you can type your note. The comment is linked to that specific text and shows your name and the date you wrote it.

Other people can see your comments and reply to them. To view all comments in a document, click the Review tab and look for the Comments section. You can delete a comment by right-clicking it and selecting Delete, or by clicking the X that appears when you hover over it.

Undoing mistakes and recovering older versions

If you make a mistake, press Ctrl+Z on Windows or Command+Z on Mac to undo your last action. You can undo multiple times to go back several steps. If you undo too much, press Ctrl+Y (Windows) or Command+Y (Mac) to redo.

If you saved a document and then made changes you want to reverse, you may be able to recover an earlier version. Click File, then look for "Info" or "Version History." If you are using OneDrive or SharePoint, you will see a list of saved versions with dates and times. Click the version you want to restore. Word opens it in a new window — if you want to keep it, click "Restore."

If you are using Word on your computer without cloud storage, older versions may not be available. This is another reason to save your work regularly — once you close and reopen a document, the old version is usually gone.

Frequently Asked Questions

Can I edit a Word document on my phone or tablet?

Yes, if you have the Word app installed on your phone or tablet, you can open and edit documents there. The app works on iPhone, iPad, and Android devices. Changes you make sync to the cloud if the document is stored on OneDrive or SharePoint, so you can pick up where you left off on another device.

What is the difference between Save and Save As?

Save (Ctrl+S) overwrites the existing file with your new changes. Save As lets you create a copy with a new name or save it in a different location. Use Save As when you want to keep the original file unchanged and work on a separate version.

Why does my document look different when someone else opens it?

Fonts, margins, and formatting can look different depending on what fonts are installed on the other person's computer, their screen size, and their Word settings. To reduce these problems, use common fonts like Arial or Times New Roman, and avoid very wide margins or unusual spacing.

Can I recover a document I accidentally deleted?

If the file is in your computer's Recycle Bin (Windows) or Trash (Mac), you can restore it from there. If it was stored on OneDrive or SharePoint, you may be able to recover it from the site's recycle bin. Local files deleted permanently are much harder to recover without special software.
