Recently, foreign media reported that Tesla is considering reducing the price of the China-made Model 3 by 20% or more next year to attract more consumers. However, the Tesla China team quickly responded, stating that they had not heard of this matter and urged consumers to refer to the official website for information.

/ Introduction /
A good idea can improve our work efficiency. If we master some shortcuts, it can help us free ourselves from tedious repetitive tasks, and the efficiency of coding will increase. Next, I want to share some practical shortcuts.
/ Main Content /
Parameter Hint
If a method’s parameters are super long and you don’t know what they are, we can use the shortcut below.
-
Mac: Cmd + P
-
Win/Linux: Ctrl + P
Auto Extract Method
When optimizing code, we often see long and messy code. Our traditional approach is to create a new function and copy the code over. This process can be completed using the shortcut below.
-
Mac: Cmd + Alt + M
-
Win/Linux: Ctrl + Alt + M
Auto Extract Parameter
During development, it is better to pass the variables used by the function as parameters. If you modify them manually, it can be tedious to change them everywhere. The shortcut below can free you from this.
Mac: Cmd + Alt + P
Win/Linux: Ctrl + Alt + P
Of course, if you just want to overload the method, check the box in the pop-up dialog.
Auto Generate Variable
-
Mac: Cmd + Alt + V
-
Win/Linux: Ctrl + Alt + V
Search Method Call
When refactoring, optimizing, or reading someone else’s code, if you want to know who called a certain method, you can use the command below.
Mac/Win/Linux: Alt + F7
Refactoring Shortcuts
During refactoring, many operations can be completed using shortcuts, but there are too many refactoring shortcuts to remember them all. There is one shortcut that can help us.
-
Mac : Ctrl + T
-
Win/Linux: Ctrl + Alt + Shift + T
Wrap Code
-
Mac: Cmd + Alt + T
-
Win/Linux: Ctrl + Alt + T
Batch Rename
If during development or optimization, you find that variable names are poorly chosen or misspelled, and you need to modify all variables used, the shortcut below can free your hands.
Mac/Win/Linux: shift + F6
View Method Call Hierarchy
Sometimes when reading code, you want to know the call structure of a method. The shortcut below will help you.
-
Mac: Control + Option + H
-
Win/Linux: Ctrl + Alt + H
View Class Hierarchy
When reading source code, if you want to know the call structure of a class, you can use the shortcut below.
-
Mac: Control + H
-
Win/Linux: Ctrl + H
Error Shortcut Hint
When writing code, you may encounter warnings given by the IDE. The shortcut below can help you effectively resolve warnings.
Mac/Win/Linux: Alt + Enter
Show All Methods of Current Class
When we are reading someone else’s code or source code, and we want to see what methods, constants, and variables the current class has, the shortcut below will give you a big picture, which is very practical.
-
MAC: Cmd + Fn + F12
-
MAC External Mechanical Keyboard: Cmd + F12
-
Win/Linux: Ctrl + F12
Highlight
When we need to see where a variable is called, this shortcut will highlight all places where this variable is used.
-
Mac: Cmd + Shift + Fn + F7
-
MAC External Mechanical Keyboard: Cmd + Shift + F7
-
Win/Linux: Ctrl + Shift + F7
Quick Jump to Parent Class
When we are reading code and want to jump to the parent class, the usual approach is to go back to the beginning of the class and click in. If the code is long, this is inefficient. The shortcut below can help you quickly jump to the parent class.
-
Mac: Cmd + U
-
Win/Linux: Ctrl + U
Quick Jump to Implementation
When an interface has multiple implementations, when we click on a method of the interface, we want to see its different implementations in subclasses. This shortcut can help you quickly jump to the implementation in subclasses.
-
Mac: Cmd + Option + B
-
Win/Linux: Ctrl + Alt + B
Override or Implement Method
This shortcut is simple; it pops up a box for you to choose which method to override or implement.
-
Mac: Control + O
-
Win/Linux: Ctrl + O
Generate Default Methods
If we want to quickly generate default methods for a class, such as constructors, toString(), Setter(), Getter(), etc., we can use the shortcut below.
-
Mac: Cmd + N
-
Win/Linux: Alt+Insert
