GNOME3 usage memorandum in Ubuntu

This article mainly describes some of the skills we often use when using GNOME3, such as shortcut keys, shelving skills, and special usage. Images will be used during the introduction to help you learn how to use them. #1. ALT + TAB: switch between applications to preview the window.

This article describes some of the skills we often use when using GNOME 3, such as shortcut keys, captioning skills, and special usage. Images will be used during the introduction to help you learn how to use them.

#1. ALT + TAB: switch between applications to preview the window.

At the same time, you can use the arrow keys to display relevant results. For example, you can use the ALT + TAB key to view the content of a Single Window before an application preview window. Use the up arrow key to return to the total preview window.

The ALT + TAB key is used to preview the application window in a forward direction. The ALT + TAB + SHIFT key can be used to preview the window in reverse direction.

#2. ALT + F2: Open the command window and enter the command to start the application.

To run the shell command in a new terminal window, press CTRL + ENTER.
#3. Maximize the window

You can drag the window to the upper edge of the screen to maximize the effect. Of course, you can double-click the title bar of the window to maximize it.

Similarly, minimize is to drag the window below the screen. You can also place a window on the left or right side of the screen to make the window layout adjacent to each other.
#4. Panel

The Panel is clear. We will not introduce this part. In particular, the "shutdown" option is hidden by default. Many users do not see the "shutdown" button during usage. You can press and hold the ALT key, and the previous "suspension" will change to "shutdown". Click it to implement the shutdown function. [This function may be modified]
#5. Window Preview

Hotspot [top left of the screen]-Move the mouse to this point to preview the window/return to the desktop.

Similarly, you can click "activity" in the upper-left corner of the screen to preview the window and return to the desktop.

To implement similar functions, you can also use the "logo key" (WIN key) or the combination key ALT + F1;

In the window preview, click the icon to start the application. If you click Application in the middle or scroll pulley, the application is started in the new work partition. This feature was not found in the past ~~

CTRL + Click the application icon to start a new window for the application in the current work partition.

You can also add applications to the "favorites" tab of the control panel ".

You can also scroll the wheel in the window preview to enlarge the preview window. Pai_^

Use CTRL + ALT + Tab to check the effect?
#6. Related return keys

When the following key combinations or functions are enabled, you can use the ESC exit key to exit:
# * ALT + TAB
# * Alt + F2
# * When you open the calendar or menu
# * When previewing a window
#7. Recording Screen

Control + Shift + Alt + R to record the screen. After you press these keys, a red circle appears in the lower right corner of the screen. The video extension for recording is. webm. Before I knew how to use this function, I recorded a video without knowing how to use it. I watched the video and saw my dumpfounded clicks. I smiled and did not know what to say. I was completely dumb!

#8. screen enlargement

You can use the "general access settings" in the upper-right corner to enlarge the screen. You can also use "gconf editor" to set/desktop/gnome/accessibility/magniier for relevant settings. I will not go into details here.
#9. Developer Tools

The Tool Name is "Looking Glass". You can press Alt + F2 and enter lg to open it. If you exit, use the ESC key.

The tool consists of four parts: Evaluator, Windows, Errors, and Extensions.

Evaluator is an interactive Javascript console. We achieved the 3D effect of yesterday through it. Refer to the article @ GNOME 3 3D effect tutorial.

After opening LG, you can enter the following code in turn under Evaluator to try it out. What is the effect?

1 + 1
 
Global. get_window_actors ()
 
Global. get_window_actors (). forEach (function (w) {Tweener. addTween (w, {time: 3, transition: 'easeoutquad ', scale_x: 0.3, scale_y: 0.3 })})
 
Global. get_window_actors (). forEach (function (w) {w. set_scale (1, 1 )})
 
Global. get_window_actors () [0]
 
It. scale_x

The other part is limited by the knowledge level of the stupid rabbit. Students with this knowledge can achieve more results.

The shortcut keys in this section are described as follows:

Press Alt + F2, enter r or resart, and restart GNOME Shell;

Press Alt + F2 and enter rt to reload the GNOME Shell topic.

Press Alt + F2 and enter debugexit to exit GNOME Shell.
