Opening and saving your document

To edit a document, you first need to open it in a program that can read that file type. If you have a Word document (.docx), open it in Microsoft Word, Google Docs, or LibreOffice Writer. If you have a PDF, use Adobe Reader or your browser. The program you chose based on your privacy needs will determine what happens next — some programs save your changes automatically to the cloud, others save only to your computer.

When you open a document, look at the top of the window for a menu bar or toolbar. In most programs, you'll see "File" as the first option. Click "File" and then "Save As" if you want to save your edited version with a new name or in a different location. This keeps your original document unchanged. If you're editing a copy you've already started, just click "Save" or press Ctrl+S (on Windows) or Command+S (on Mac) to save your changes to the same file.

Pay attention to where your program saves files by default. Microsoft Word and Google Docs save to the cloud unless you change the setting. LibreOffice Writer and most offline editors save to your computer's hard drive. If privacy matters to you, check your program's settings before you save — you may need to turn off cloud sync or choose a local folder instead.

Key Takeaways

  • Open your document in a program that matches the file type: Word documents in Word or LibreOffice, PDFs in Adobe Reader or your browser.
  • Use "File" then "Save As" to save an edited copy with a new name, or "Save" to overwrite the original with your changes.
  • Check where your program saves by default — cloud storage or your computer — because this affects your privacy and whether others can see your edits.
  • Most programs use Ctrl+S (Windows) or Command+S (Mac) as a keyboard shortcut to save quickly while you work.
  • If you're working in a shared document, understand whether changes are tracked automatically or whether you need to turn on "Track Changes" to show what you edited.

Selecting and deleting text

To change text, you first need to select it. Click at the beginning of the text you want to edit, then drag your mouse to the end of it. The selected text will highlight in blue (or another color depending on your program). You can also double-click a single word to select just that word, or triple-click to select an entire paragraph.

Once text is selected, you can delete it by pressing the Delete key or Backspace. You can also type new text to replace it — just start typing and the selected text will disappear. If you delete something by accident, press Ctrl+Z (Windows) or Command+Z (Mac) to undo the last action. You can undo multiple times to go back several steps.

A faster way to select text is using keyboard shortcuts. Hold Shift and press the right arrow key to select one character at a time, or hold Shift and click at the end of the text you want to select. This is useful if your mouse isn't working well or if you're editing on a laptop trackpad.

Copying, cutting, and pasting text

If you want to move text from one place to another without losing it, use cut and paste. Select the text, then press Ctrl+X (Windows) or Command+X (Mac) to cut it. The text disappears from where it was. Click where you want to put it and press Ctrl+V (Windows) or Command+V (Mac) to paste it there.

If you want to copy text instead of moving it, select the text and press Ctrl+C (Windows) or Command+C (Mac). The original stays where it is, and you can paste a copy anywhere else in the document or in a different document. This is useful when you're repeating information or building on something you've already written.

Be careful when pasting text from websites or other documents — sometimes the formatting (bold, italics, colors, fonts) comes along with the words. If you want just the plain text without the formatting, use "Paste Special" instead of regular paste. In most programs, this is under the "Edit" menu. Choose "Paste Special" and then select "Unformatted Text" or "Plain Text".

Finding and replacing text

If you need to change the same word or phrase throughout a document, use Find and Replace instead of editing each one by hand. Press Ctrl+H (Windows) or Command+H (Mac) to open the Find and Replace dialog. Type the text you want to find in the first box and the text you want to replace it with in the second box.

Click "Replace All" to change every instance at once, or click "Replace" one at a time if you want to check each change before it happens. This is especially useful in long documents where the same term appears dozens of times. For example, if you wrote "the company" throughout a document but now want to use the actual company name, Find and Replace does this in seconds.

If you just need to find text without replacing it, press Ctrl+F (Windows) or Command+F (Mac) to open the Find toolbar. Type what you're looking for and the program will jump to each instance in your document. This helps you locate information quickly without scrolling through the whole file.

Formatting text: bold, italics, and fonts

To make text bold, select it and press Ctrl+B (Windows) or Command+B (Mac). To make it italic, press Ctrl+I (Windows) or Command+I (Mac). To underline text, press Ctrl+U (Windows) or Command+U (Mac). You can also click the Bold, Italic, or Underline buttons in the toolbar at the top of your program — they usually look like a "B", an "I", and a "U".

To change the font or font size, select the text first. Look for a dropdown menu in the toolbar that shows the current font name (like "Arial" or "Times New Roman"). Click it to see other fonts available. Next to it is usually another dropdown showing the font size in points — 12 point is standard for body text, but you can make it larger for headings or smaller for footnotes.

Most programs also let you change text color. Select the text, then look for a button that looks like an "A" with a colored bar underneath. Click the small arrow next to it to choose a new color. Use color sparingly — too many colors make a document hard to read. Bold and larger fonts are usually better for making important text stand out.

Adding and editing headings

Headings organize your document and make it easier to read. To create a heading, select the text you want to turn into a heading, then look for a "Styles" menu or a dropdown that says "Normal" or "Body Text". Click it and choose "Heading 1" for your main headings, "Heading 2" for subheadings, and so on. Headings are usually larger and bolder than regular text, and they help readers scan your document quickly.

If you use headings, many programs can automatically create a table of contents for you. In Microsoft Word, go to the "References" tab and click "Table of Contents". In Google Docs, go to "Insert" and then "Table of Contents". The program reads your headings and builds a clickable list. If you add or change a heading later, you can update the table of contents with one click.

Avoid using bold or large fonts instead of real headings — they look the same to you, but the program doesn't recognize them as headings. This matters if you need to create a table of contents, print to PDF, or share the document with someone using a screen reader.

Working with lists and tables

To create a bulleted or numbered list, click where you want the list to start. Look for a button in the toolbar that looks like three horizontal lines with dots (for bullets) or numbers. Click it and start typing. Press Enter at the end of each item to create a new bullet or number. Press Enter twice to end the list and return to normal text.

If you need to organize information in rows and columns, insert a table. Go to the "Insert" menu and choose "Table". Tell the program how many rows and columns you need, and it will create an empty table. Click in each cell and type your information. You can add or delete rows and columns later by right-clicking inside the table and choosing the option you need.

Tables are useful for comparing options, showing schedules, or listing steps in order. Don't use a table just to make text look organized — use it only when information genuinely belongs in rows and columns. A table with one column or one row is usually a sign you should use a list instead.

Tracking changes and comments

If someone else will review your document, turn on "Track Changes" so they can see what you edited. In Microsoft Word, go to the "Review" tab and click "Track Changes". In Google Docs, click the pencil icon in the top right and choose "Editing". Now every change you make — text you add, delete, or format — will be marked with a different color and your name. The reviewer can accept or reject each change.

You can also add comments to explain your edits. Select the text you want to comment on, then press Ctrl+Alt+M (Windows) or Command+Option+M (Mac) in Word, or click the comment button in Google Docs. Type your comment and it will appear in a sidebar. Comments are useful when you're asking a question or explaining why you made a change.

If you're reviewing someone else's tracked changes, you'll see insertions in one color and deletions in another. Click "Accept" to keep a change or "Reject" to remove it. You can accept all changes at once or go through them one by one. This is standard practice when multiple people work on the same document.

Frequently Asked Questions

What's the difference between Save and Save As?

Save overwrites your current file with the new version. Save As creates a copy with a new name or in a new location, leaving the original unchanged. Use Save As when you want to keep multiple versions or when you're editing a template and don't want to change the original.

Can I undo changes after I've saved the document?

Yes, but only back to your last save. Once you close and reopen a document, the undo history is gone. If you need to recover an older version, check your program's version history or backup settings — Google Docs and Microsoft Word both keep previous versions for a limited time.

How do I know if my document is saved to the cloud or my computer?

Check the title bar at the top of your window. If it shows a cloud icon or says "OneDrive" or "Google Drive", it's in the cloud. If it just shows a file name with no cloud indicator, it's saved locally. You can also go to File > Properties or File > Info to see the full file path and location.

What should I do if my document won't open?

Try opening it in a different program. A .docx file can open in Word, Google Docs, or LibreOffice. A .pdf opens in Adobe Reader, your browser, or most PDF viewers. If it still won't open, the file may be corrupted. Try downloading it again or asking the person who sent it to resend it.

Can I edit a document on my phone or tablet?

Yes, if it's stored in the cloud. Google Docs, Microsoft Word Online, and Apple Pages all have mobile apps. read the app, sign in, and open your document. Editing on a small screen is slower than on a computer, but it works for quick changes. Offline editing on phones is limited — most programs require an internet connection.
