7.8 Run
[Run] menu provides the ability to direct commands to the system without using the menu in the window, clicking the icon, or using the Shell Terminal screen.
● Execution screen
When you execute this menu, a pop-up screen will appear, allowing you to enter commands on the screen as shown below. Here, when the user inputs a desired command to be processed and presses the [OK] button, the command is executed.
7.7.3 Main Menu Editor
This program can define a list of programs that can be run directly from the window’s menu.
If Application Menu Menu à Preference à Main Menu Editor is executed, a pop-up screen to configure setting appears.
First, if the [Applications] menu on the left side of the screen is selected, the list of menus available at the top level appears on the right. Here you can select the desired menu and adjust what you need. Then, when you select the top menu again under [Applications] on the left side of the screen, a submenu list below it appears on the right. Here again, you can select the desired menu and adjust the necessary content.
7.7.2 Theme and Appearance Settings
This program defines the properties of the items inside the window. It can define the contents of various items such as desktop screen and icons.
If you run Application Menu Menu → Preferences → Theme and Appearance Settings, the screen as follows for settings appears.
7.7 Preference
7.7.1 Mouse and Keyboard Settings
This program provides the ability to adjust settings for the mouse and keyboard.
If you execute Application Menu Menu → Preferences → Mouse and Keyboard Setting, the screen for setting task as shown below appears.
7.6.2 Raspberry Pi Help
With Application Menu Menu à Help à Raspberry Pi Help, you can view related materials. Here you can view the Help material provided on the official website of Raspberry Pi. The URL is as follows:
■ http://www.raspberrypi.org/help/
7.6 Help
7.6.1 Debian Reference
Raspberry Pi allows you to view Help materials for Debian which is the base for Raspbian. These materials are stored in the Raspberry Pi system itself. The related URL is as follows:
■ file:///usr/share/debian-reference/index.html
7.5.4 Game
The Raspberry Pi system offers a number of games by default, meaning that it not only allows users to play games simply on the Raspberry Pi system, but also gives users an opportunity to develop their ability to develop programs through games with Python. It allows users to interact with the game using Python, and provides an environment in which users can change and execute the contents of the program source code of the game.
How to communicate with Game with Python is described again in detail in [23.5.6 Learning Python through Game].
7.5.3 Internet Web Browser (EpicHany)
In the Raspberry Pi system, EpicHany webbrowser is provided as a default. Previous versions provided several browsers, but this browser is adopted by default because it is relatively light and provides good performance. The screen below is the screen that executes the browser.
The tools on the top right let you do a variety of tasks, and you have the ability to perform the various setup tasks according user’s need during the execution process.
7.5.2 Programming Tool
Here, we will briefly discuss the basic programming tools provided by Raspberry Pi. For more details, Please refer to the description of [Chapter 23 Writing Program].
7.5.2.1 Mathematica & Wolfram Language
Mathematica is a professional numerical programming tool that makes it easy to perform necessary specialized mathematical calculations in science, mathematics, computer science, and engineering, and was developed in 1988 by Wolfram Research. Mathematica is a popular tool for complex and specialized mathematical calculations, such as differential and integral calculations, and it can do huge calculations quickly.
7.5 Overview of Key Execution Program
7.5.1 Accessories
7.5.1.1 File Manager (PCManFm)
This program provides the ability to search and query all the data in the system. It has a function similar to [Explorer] of MS Windows. The Raspberry Pi system is characterized by the fact that all information is managed as a file, and much more information can be retrieved.
