- On the main menu, choose , or press Ctrl+Shift+Alt+I.

Using live templates for smart completion of parameters in function calls
IntelliJ IDEA has an “automatic” live template that provides completion lists for the parameters passed into functions, methods, or class constructors.
- To activate this functionality:
To invoke the magic live template, type the params keyword as the first parameter
in the call of the function, method, or class:
IntelliJ IDEA displays a live template where the parameters are automatically completed with the variable names defined in the function declaration.
To move to the next parameter, press Enter or Tab.
To move to the previous parameter, press Shift+Tab.
The completion list contains variables from a local scope in the next order: with the same type, with a similar name, defined nearby. You can always switch to the usual completion mode by pressing Ctrl+Space or just typing anything which is not in the list. Variables with similar names are inserted automatically.
