Time	Narration
00:01	Welcome to the Spoken Tutorial on Handling tabs in gedit Text editor.
00:04	In this tutorial, we will learn to: Add, move, re-order and close tabs
00:13	Use the Side Panel to browse and open files
00:19	Insert line numbers and Wrap text.
00:22	To record this tutorial, I am using: Ubuntu Linux 14.04 operating system gedit 3.10
00:32	To follow this tutorial, you should have working knowledge of any operating system.
00:38	Let's open the gedit Text editor.
00:42	By default, the gedit Text editor has one tab named as Untitled Document 1.
00:49	Now, pause the tutorial and type the following code as displayed on the screen.
00:56	This is a program in C language.
00:58	Let us save the program.
01:01	Press Ctrl + S keys simultaneously on the keyboard.
01:06	In the Save dialog-box, enter the name as sample dot c.
01:11	The extension ‘c’ indicates that it is a C language program.
01:16	Select the folder where you want to save the file.
01:20	I will select Desktop and then click on Save button.
01:25	The tab name has changed to sample dot c.
01:29	Did you notice the various colors in the program after you saved the file?
01:35	This is because gedit Text editor recognizes the typed code as a C program.
01:42	We will learn more about syntax highlighting in later tutorials.
01:47	Also, notice the status bar which has changed to 'C'.
01:52	We can see that the window name has also changed to sample dot c.
01:57	To add a new tab, from the Main menu, click File and New.
02:04	A new tab named Untitled Document 1 is created to the right of the document sample.c.
02:12	Again, the title at the top of the window has changed to Untitled Document 1.
02:18	So, the name of the active tab is displayed as the title of the window.
02:23	Now, let’s learn another way to open a new tab.
02:27	Click on the New icon in the toolbar.
02:31	Another tab Untitled Document 2 has been created.
02:35	The numbering of tabs begins at 1 and increments by 1 for each new tab that is opened.
02:43	That’s why this tab is numbered 2.
02:47	In a similar way, let's create two more new documents.
02:52	Now, we have a total of 5 tabs including sample.c.
02:58	How do we navigate through these tabs?
03:01	Notice, there is a triangular button on both ends of the tab bar.
03:07	You can use these buttons to navigate through the tabs.
03:12	Let's click on the left triangular button till the document sample.c is visible.
03:19	How do we close the tabs? This is very simple.
03:22	From the Main menu, click File and Close.
03:27	Alternately, you can simply click on the 'X' button on the tab.
03:32	Let's close the Untitled Document 2 and 3 in this manner.
03:39	So, we are left with sample dot c, Untitled Document 1 and Untitled Document 4.
03:47	Now, let's add two more new documents.
03:52	These two new tabs are named as Untitled Document 2 and 3.
03:57	The documents are numbered or ordered as shown here.
04:03	The ordering may be different in lower versions of gedit.
04:08	Such differences in versions will happen and the learner should be prepared to handle these.
04:15	Let's rearrange the tabs now.
04:18	First, select Untitled Document1.
04:21	Press the left mouse button and drop it to the left of the file sample.c.
04:27	Release the left mouse-button.
04:30	The tab is rearranged.
04:33	In the same manner, let us rearrange the tab 2 and 4.
04:38	Next, let's learn to move a tab to another window.
04:42	First, select the tab sample.c which we want to move.
04:47	Then, right-click on the tab and select 'Move to New Window'.
04:52	sample.c opens in a new window.
04:56	Let's switch from sample.c to the other window with the Untitled Documents.
05:02	Go to the Main menu and click View and Side Panel.
05:07	The Side Panel opens up on the left side of the window.
05:12	You can view the names of all the documents in the side panel.
05:17	It is in the same order in which they appear on the window panel.
05:22	In the side panel, click on the Untitled Document 2.
05:27	That document becomes active now.
05:31	Let us rearrange the document in the gedit Text editor window as we did before.
05:37	Let’s click on the tab Untitled Document 4.
05:40	Click, drag and drop the file after the last tab.
05:46	Notice that the document order has now changed in the side panel, too.
05:52	To close the side panel, simply click the 'X' button on the top right.
05:58	Let's learn how to go to a specific line number in the gedit Text editor file.
06:04	Switch to sample.c file.
06:07	From the Main menu, click Search and Go to Line.
06:12	The Go to Line dialog-box appears on the top right corner of the gedit Text editor window.
06:20	In the dialog-box, enter the number 8 and press the Enter key.
06:26	The cursor jumps to line 8. We can also see the line number as 8 in the status bar.
06:33	But, it will be easy to locate the cursor if the line number is displayed along with the text.
06:40	To display the line numbers of the code, from the Main menu, select Edit and Preferences.
06:47	gedit Preferences dialog-box appears.
06:50	Click the View tab.
06:52	Put a checkmark on Display line numbers option.
06:56	Put a checkmark on Highlight current line option. Click on the Close button.
07:04	Notice that the line numbers are displayed to the right of the code.
07:09	Also, the line on which your cursor is displayed is in bold.
07:14	Next we will learn about text wrapping.
07:18	A line of code in a program may exceed the length of the gedit Text editor window.
07:24	So, it becomes difficult to read the entire line of the text.
07:29	Text wrapping helps to wrap the text within the size of the window.
07:34	Switch back to the sample.c program.
07:37	From the Main menu, click Edit and then Preferences.
07:43	Notice that the option Enable text wrapping is checked by default.
07:50	Uncheck this box. Click on the Close button.
07:55	Let me add a line of code at the end of the program.
08:00	Notice that the length of the text has exceeded the size of the window.
08:05	Now, let's check the option Enable text wrapping.
08:10	The text has been neatly wrapped to fit the window.
08:15	This brings us to the end of this tutorial. Let us summarise.
08:20	In this tutorial, we learnt to: Add, move, re-order and close tabs
08:26	* Use the side panel to browse and open files
08:30	* Insert line numbers and Wrap text.
