Tips & Tricks
Double Shift to Search Everywhere
Read this post in other languages:
As a user of IntelliJ IDEA, you may often find yourself wanting to increase your productivity by limiting the use of your mouse in your daily work.
With IntelliJ IDEA, you really only have to know a basic set of shortcuts, since you can use the Search Everywhere window to access anything you need.
For example, you can search for shortcuts that you don’t remember, actions you rarely use in your work, or actions that don’t have shortcuts assigned to them. Search Everywhere can also help you access main menu actions, tool windows, and settings.
Press Shift twice to open the Search Everywhere window, and then just enter your query to search inside your project. By the way, you can include non-project items in your search if you’d like to see, for example, search results from external libraries.
When IntelliJ IDEA opens the Search Everywhere window, it conveniently shows you a list of recent files that you can access.
You can change the scope of your search by switching between tabs to view the results from classes, files, symbols, or actions.
You can access the main menu actions right from the Search Everywhere window by typing the name of the menu option in the search field.
Let’s say, for example, that you work in distraction-free mode and want to exit IntelliJ IDEA. Type “exit” in the search field and hit Enter.
You can access any tool window by typing its name as your search query.
You can also browse a list of settings without leaving the working environment. Just type “/” before the query, and the Search Everywhere window will show you the groups of settings.
You can enable or disable options in the settings without leaving the Search Everywhere window. Enter a name or use groups of settings to locate the option you want to toggle, select the option in the list of the search results, and use the ON/OFF control keys. By the way, you can achieve the same outcome with plugins if you type “/plugins “ in the search field – this will give you a list of plugins in the search results which you can enable or disable.
Sometimes, the settings’ option you are looking for may have been moved to a different location. With the Search Everywhere window, you can keep track of those relocations since IntelliJ IDEA displays the paths to the listed options. Additionally, you can access those options right from the window.
When you find an action that doesn’t have a shortcut assigned to it, you can assign your own right from the Search Everywhere window. Type the name of the action in the search field, press Alt + Enter, and enter the shortcut in the Keyboard Shortcut dialog.
Search Everywhere can save you a lot of time, increase your productivity, and help you learn new shortcuts. All you need is to press Shift twice.
Happy Developing!

Вот новичок, который использует Python3 без написания Python3. Пожалуйста, содержим много и легко распылите его.
Python3 управляется PymySQL, код выглядит следующим образом [из учебника Cainiao]:
#!/usr/bin/python3
import pymysql
# Откройте подключение к базе данных: адрес, имя пользователя, пароль, имя базы данных
db = pymysql.connect("IP -адрес конфиденциально", "Конфиденциально имени пользователя", "Конфиденциальность пароля", «Имя базы данных конфиденциально»)
# Используйте метод Cursor () для создания курсора объекта курсора
cursor = db.cursor()
# Используйте метод execute () для выполнения SQL -запроса
cursor.execute("SELECT VERSION()")
# Используйте метод fetchone (), чтобы получить единые данные
data = cursor.fetchone()
print("Database version : %s " % data)
# Close Batabase Connection
db.close()
1. Нет модуля под названием PymySQL
Первая ошибка, которая появилась:
Сначала проверьте, существует ли PymySQL в командной строке:pip3 install PyMySQL
Дисплей командной строки:Requirement already satisfied: PyMySQL in c:\users\admin\appdata\local\programs\python\python37\lib\site-packages (0.9.3)
Это показывает, что PymySQL уже должен существовать.
Решение заключается в следующем:
Новые проекты проверяют наследство глобальных пакетов на сайтах и делают доступность для всех проектов. Скопируйте код еще раз, то есть больше не появляется в этой ошибке
2. Не могу бежать
Установлено, что приведенный выше код не может быть запущен напрямую. Поэтому скопируйте базовый код в код шаблона, предоставленный Pycharm. Код обновляется следующим образом:
# This is a sample Python script.
# Press Shift+F10 to execute it or replace it with your code.
# Press Double Shift to search everywhere for classes, files, tool windows, actions, and settings.
import pymysql
#ДВА -линейные пространства между функциями и функциями должны быть
def print_hi(name):
# Use a breakpoint in the code line below to debug your script.
print(f'Hi, {name}') # Press Ctrl+F8 to toggle the breakpoint.
def db_connect():
# Откройте подключение к базе данных: адрес, имя пользователя, пароль, имя базы данных
db = pymysql.connect("IP -адрес конфиденциально", "Конфиденциально имени пользователя", "Конфиденциальность пароля", «Имя базы данных конфиденциально»)
# Используйте метод Cursor () для создания курсора объекта курсора
cursor = db.cursor()
# Используйте метод execute () для выполнения SQL -запроса
cursor.execute("SELECT VERSION()")
# Используйте метод fetchone (), чтобы получить единые данные
data = cursor.fetchone()
print("Database version : %s " % data)
# Close Batabase Connection
db.close()
# Press the green button in the gutter to run the script.
if __name__ == '__main__':
print_hi('PyCharm')
db_connect()
print_hi('PyCharm')

I wasn’t aware of the double-shift until I read your comment. Thanks much for teaching me something new today! 
I use Control+N to search for classes mostly. To run and to stop. I have extra keys on my keyboard that I’m able to run macros. One of them runs the program currently visible in PyCharm (Control+Alt+R). Another one stops it if pressed once or stops everything if pressed twice (Control+F2).
For running most of my PySimpleGUI Demo Programs, I use the Demo Program Browser (launches using another single-key).
Anyway, thanks for the great tip.
Motivation : There is a project code in the Windows local system, which needs to be uploaded to the server and run the code using the server-side python environment. When the local code changes, the server-side code is synchronized in real time.
1. Install pycharm professional version
Note: You need to install the pycharm professional version. The community version lacks remote debugging functionality.
2. Create a new demo project locally
The path where the project is located: D:\Codes\python\local, the main.py code is as follows:
# This is a sample Python script.
# Press Shift+F10 to execute it or replace it with your code.
# Press Double Shift to search everywhere for classes, files, tool windows, actions, and settings.
def print_hi(name):
# Use a breakpoint in the code line below to debug your script.
print(f'Hi, {name}') # Press Ctrl+F8 to toggle the breakpoint.
# Press the green button in the gutter to run the script.
if __name__ == '__main__':
print_hi('PyCharm')
# See PyCharm help at https://www.jetbrains.com/help/pycharm/Running python main.py gets the following output:
3. Configure remote connection
Click Tools->Deployment->Configuration
Click +->SFTP
Name the server. You can name it whatever you want. Here it is named 253.
Click…
Click +
Setting parameters
Click OK
Set server path
That is to say, pycharm will synchronize the local code in D:\Codes\python\local to the server /home1/users/XXX/Codes/fromlocal/ path.
Click Tools->Deployment->Options
Change the option, it means that every time we Ctrl+S save, the code will be synchronized once
4. Upload project code
Right-click the project that needs to be uploaded and upload it to the 253 server created in step 3.
The uploaded file appears under the corresponding path of the server.
5. Configure the python environment
Click File->Settings
Add python environment
6. Configure the running environment of main.py
7. Run and test synchronization
Change the code on the local side:
# This is a sample Python script.
# Press Shift+F10 to execute it or replace it with your code.
# Press Double Shift to search everywhere for classes, files, tool windows, actions, and settings.
def print_hi(name):
# Use a breakpoint in the code line below to debug your script.
print(f'Hi, {name}') # Press Ctrl+F8 to toggle the breakpoint.
# Press the green button in the gutter to run the script.
if __name__ == '__main__':
print_hi('PyCharm')
print('test1: change from local')
# See PyCharm help at https://www.jetbrains.com/help/pycharm/
Run again to achieve synchronization:
8. Call the server terminal to run
Create a new terminal
Enter the project path and run, you can get the same result
Change local main.py
# This is a sample Python script.
# Press Shift+F10 to execute it or replace it with your code.
# Press Double Shift to search everywhere for classes, files, tool windows, actions, and settings.
def print_hi(name):
# Use a breakpoint in the code line below to debug your script.
print(f'Hi, {name}') # Press Ctrl+F8 to toggle the breakpoint.
# Press the green button in the gutter to run the script.
if __name__ == '__main__':
print_hi('PyCharm')
print('test1: change from local')
print('test2: change from local')
# See PyCharm help at https://www.jetbrains.com/help/pycharm/
Ctrl+S save and run again to achieve synchronization.
Therefore, when running in both ways, local changes can be synchronized in real time on the server side.
PyCharm is a widely used Integrated development environment(IDE) for Python programming language. Moreover, Pycharm provides a very useful working environment for Odoo development. On a different note a shortcut is a method of achieving something more quickly or more easily than if you use the usual methods.
