Slide 1:	Welcome to the Spoken Tutorial on Handling tabs in gedit Text editor.
Slide 2: Learning objectives	In this tutorial, we will learn to: Add, move, re-order and close tabs Use the Side Panel to browse and open files Insert line numbers and Wrap text
Slide 3: System Requirements	To record this tutorial, I am using: Ubuntu Linux 14.04 operating system gedit 3.10
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 2and 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 pane.
In the Side Pane, click on Untitled Document 2.	In the Side Panel, click on the Untitled Document 2. That document becomes active.
	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.

Click Search >> Go to line	From the Main menu, click Search and Go to Line.
Point to the Go to Line dialog box	The Go to Line dialog-box appears on the top right corner of the gedit Text editor window.
Enter 8 in the box	In the dialog box, enter the number 8 and press the Enter key.
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.

Slide 5: Text Wrapping	Next we will learn about text wrapping. A line of code in a program may exceed the length of the gedit Text editor window. So, it becomes difficult to read the entire line of the text. Text wrapping helps to wrap the text within the size of the window.
Switch back to the sample.c program.	Switch back to the sample.c program.
Click Edit >> Preferences	From the Main menu, click Edit and then Preferences.
Point to the check box Enable text wrapping	Notice that the option Enable text wrapping is checked by default.
Uncheck the box. Click Close.	Uncheck this box. Click on the Close button.

Click Edit >> Preferences Click on the View tab. Check the option Enable text wrapping Click Close.	Now, let's check the option Enable text wrapping.
Point to the text to show text wrapping.	The text has been neatly wrapped to fit the window. <<PAUSE>>
