IntelliJ replace variable names in multiple lines

Question

I am wondering is there a shortcut that can replace a variable name with a new name on multiple lines in the current Java file for IntelliJ. Is it just simply doing a find and replace operation, but it can't really solve the problem obviously.

Answer 1

Try to set cursor on variable and use shortcut Shift-F6 - after that there are dialog frame for change name of variable and it changes all occurences of variable to setted name.

Also, you can use shortcut Ctrl-Shift-R for replacing any word in project, it is useful if you working with huge project or your variable appears in config files.
