Alt+Shift+M Extract the code in a function into a method (this is one of the most common methods in refactoring, especially useful for a lot of mud code)
Alt+Shift+ C Modify the function structure (more practical, there are N functions that call this method, modify it once)
Alt+Shift+L Extract local variables (You can directly extract some magic numbers and strings into a variable, especially if it is called multiple times time)
Alt+Shift+F Change the local variable in the Class into a field variable (a more practical function)
