Introduction to Text Editing
In the previous chapter, you created a document on gender equality. You also learnt how to create, save, search, open, and share a document. In this chapter, you will learn how to edit text in documents.
Text editing in Google Docs is the process of making changes to the text to improve its clarity and accuracy. It can also include copying, deleting, and moving the text.
Editing Text
Once you type the text in any document, you may want to make some changes to that text. For example, if you want to add some text about the topic, ‘Challenges to Gender Equality’ in the ‘Gender Equality’ document, you can do it by following the steps given below:
1. Place your cursor where you want to add the text. Press the Enter key.
2. Enter the name of the topic. In our case, it is ‘Challenges to Gender Equality’. After writing it, press the Enter key.
3. Type the text that you want to enter.
Selecting Text
After typing the text, you can perform many operations on it, like deleting the text, duplicating the text, etc. For this, you need to first select the text. You can select a letter, a word, a block of text, a paragraph, or the complete document.
Selecting text using a mouse:
1. A word: Double-click on the word.
2. A paragraph: Triple-click anywhere on the paragraph.
3. A block of text: Click at the beginning of the text, drag over it, and then release the mouse button.
4. Complete document: Click on the Edit menu and choose the Select all option.
Selecting text using a keyboard:
1. A character to the left of the cursor: Press the Shift + Left Arrow keys.
2. A character to the right of the cursor: Press the Shift + Right Arrow keys.

Copying and Pasting Text
If you have a word that you want to use many times in your document, then instead of typing it again and again, you can just copy and paste it wherever you need it.
In this way, you save time and do not have to keep typing the same word over and over.
Copying text means duplicating the selected text and making it available for another location.
Pasting means putting something you copied from one place into another in the same document or another document.
Suppose you want to continue typing, and you have to start the paragraph with ‘Gender equality.’ Instead of typing it again, you can just copy it from the top part of the document and paste it at the point where you have to type it again.
Steps to Copy the Text
You can copy the text with a keyboard or a mouse. Using the keyboard, press the Ctrl and C keys together. The steps to copy the text using a mouse are given below:
1. Select the text that you want to copy. 1 Copied text

Moving Text
While editing text, you might realise that some text is in the wrong place and needs to be moved elsewhere.
Moving text means removing it from its original position and placing it at some other position in the document.
We can move text using the Cut and Paste commands. The Cut command removes the text from its original position.
Let us see how we can move the text.
In the above document, for example, you want to change the position of a paragraph from its original position and place it before ‘Challenges to Gender Equality’. Steps to move the text are given below:
1. Triple-click on the first line of the paragraph you want to move to select the complete paragraph.
2. Click on the Edit menu.
3. Select the Cut option or press the Ctrl and X keys together.
4. Place the cursor where you want to paste the text and click on the Edit menu.
5. Select the Paste option.
Think and Tell
Do you think changing the text colour is also a part of text editing?
Deleting Text
If, in your document, you write something by mistake that you want to remove, then the Delete key is used.
The Delete key is used to erase a word, line, or paragraph that you want to remove from your document.
For example, in our document, we want to delete the word ‘Gender Equality’ from the end of the document. To do that, we will follow the steps below:
1. Select the text.
2. Press the Delete key. It will erase the selected text. You can also delete the text using the Backspace key.
3. Type the new word if needed.
Undo
How can you replace text without deleting the original text?
If you do something wrong in your document by mistake, Undo can reverse the change.
Undo is the command which can reverse the last action.
For example, you have mistakenly deleted the text ‘Gender equality’ in your document, but you didn’t like it, so you want to change it back to the original one.
Undo can be done in three different ways:
Click on the Undo button from the Toolbar. or
Click on Edit menu and then select the Undo option. or Press the Ctrl + Z keys together.
Redo
Redo will reverse the last action of the Undo command.
If you need to reverse the action of the Undo command, it can be done by the Redo command.
You will see that the text will be deleted again.
Redo can be done in three different ways:
Click on the Redo button from the Toolbar. or
Click on the Edit menu and then select the Redo option. or
