Slide 4:
Pre-requisites |
To follow this tutorial, you should have working knowledge of any operating system. |
Let's open the gedit Text editor. | |
Point to the tab | By default, the gedit Text editor has one tab named as Untitled Document 1. |
Copy and paste the code | Now, pause the tutorial and type the following code as displayed on the screen. |
Point to the C program | This is a program in C language. |
Let us save the program. | |
Ctrl + S | Press Ctrl + S keys simultaneously on the keyboard. |
Enter Name >> Sample.c | In the Save dialog box, enter the name as sample dot c.
The extension ‘c’ indicates that it is a C language program. |
Browse >> Select Desktop
Click Save. |
Select the folder where you want to save the file.
I will select Desktop and then click on Save button. The tab name has changed to sample dot c. |
Point to the different colors
Point to the status bar |
Did you notice the various colors in the program after you saved the file?
This is because gedit Text editor recognizes the typed code as a C program. We will learn more about syntax highlighting in later tutorials. Also, notice the status bar which has changed to 'C'. |
Point to the top bar of the window | We can see that the window name has also changed to sample dot c. |
From the Main menu, click File>>New | To add a new tab, from the Main menu, click File and New. |
Point to the Untitled Document1 | A new tab named Untitled Document 1 is created to the right of the document sample.c. |
Point to the top bar of the window | Again, the title at the top of the window has changed to Untitled Document 1.
So, the name of the active tab is displayed as the title of the window. |
Click >> New icon from the toolbar | Now, let’s learn another way to open a new tab.
Click on the New icon in the toolbar. |
Point to untitled Document 2 | Another tab Untitled Document 2 has been created.
The numbering of tabs begins at 1 and increments by 1 for each new tab that is opened. That’s why this tab is numbered 2. |
Click 'New' icon twice in the toolbar | In a similar way, let's create two more new documents. |
Point to all tabs | Now, we have a total of 5 tabs including sample.c. |
How do we navigate through these tabs? | |
Point to the triangular button on both ends of the tab bar | Notice, there is a triangular button on both ends of the tab bar. |
You can use these buttons to navigate through the tabs. | |
Click on the left triangular button | Let's click on the left triangular button till the document sample.c is visible. |
How do we close the tabs?
This is very simple. | |
Main Menu >> File >>Close | From the Main menu, click File and Close |
Point to the X button on the tab | Alternately, you can simply click on the X button on the tab. |
Close Untitled Document 2 and 3 | Let's close the Untitled Document 2 and 3 in this manner.
So, we are left with sample dot c, Untitled Document 1 and Untitled Document 4. |
Click New icon twice in the toolbar | Now, let's add two more new documents. |
Point to Untitled Document 2 and 3 | These two new tabs are named as Untitled Document 2 and 3. |
The documents are numbered or ordered, as shown here. | |
The ordering may be different in lower versions of gedit.
Such differences in versions will happen and the learner should be prepared to handle these. | |
Let's rearrange the tabs now. | |
Select Untitled Document1. | First, select Untitled Document1. |
Press the left mouse button and drag it to the left. | Press the left mouse button and drop it to the left of the file sample.c. |
Release the left mouse button | Release the left mouse button. |
Point to the tab that is rearranged. | The tab is rearranged. |
Rearrange the tab 2and 4 | In the same manner, let us rearrange the tab 2 and 4.
<<PAUSE>> |
Next, let's learn to move a tab to another window. | |
Select the tab where sample.c is present | First, select the tab sample.c which we want to move. |
Right click on the tab and select 'Move to New Window'
Point to sample.c that opens in new window |
Then, right-click on the tab and select 'Move to New Window'.
sample.c opens in a new window. |
Let's switch from sample.c to the other window with the Untitled Documents. | |
Main menu >> View >> Side Pane | Go to the Main menu and click View and Side Panel. |
Point to the Side Pane on the left side of the window | The Side Panel opens up on the left side of the window. |
You can view the names of all the documents in the Side Panel.
It is in the same order in which they appear on the window panel. | |
In the Side Pane, click on Untitled Document 2. | In the Side Panel, click on the Untitled Document 2.
That document becomes active now. |
Let us rearrange the document in the gedit Text editor window, as we did before. | |
Click on the tab Untitled Document 4.
Press the left mouse button and drag and drop the file after the last tab. |
Let’s click on the tab Untitled Document 4.
Click, drag and drop the file after the last tab. |
Point to the changes in the Side Pane. | Notice that the document order has now changed in the Side Panel, too. |
To close the Side Pane, simply click the X button on the top right. | To close the Side Panel, simply click the X button on the top right.

Let's learn how to go to a specific line number in the gedit Text editor file. | |
Switch to sample.c file. | Switch to sample.c file. |
Click Search >> Go to line | From the Main menu, click Search and Go to Line. |

Point to the cursor
Point to the status bar |
The cursor jumps to line 8.
We can also see the line number as 8 in the status bar. |
But, it will be easy to locate the cursor if the line number is displayed along with the text. | |
Click Edit >> Preferences | To display the line numbers of the code, from the Main menu, select Edit and Preferences. |

Click on the Close button. |
Point to the line numbers
|
Notice that the line numbers are displayed to the left of the code.
Also, the line on which your cursor is displayed is in bold. <<PAUSE>> |
Slide 5:

Point to the line where it exceeds the window length. | Notice that the length of the text has exceeded the size of the window. |
Click Edit>> Preferences
