How to move the cursor to the correct indentation level without quiting insert mode?

Question

For example I have this JavaScript code. The | character represents the cursor position and it is on an empty line.

function a() {
    console.log("a");

    function b() {
        console.log("b");

        function c() {
            console.log("c");
        }
|
        c();
    }

    b();
}

After the requested operation, the contents would look like this:

function a() {
    console.log("a");

    function b() {
        console.log("b");

        function c() {
            console.log("c");
        }
        |
        c();
    }

    b();
}

What I am asking for is a mapping command.

Answer 1

As @jamessan mentioned, <C-f> will indent to the correct place from insert mode. You can also use <C-t> and <C-d> to increase or decrease the indention level from insert mode.

However, you may be able to avoid getting into that situation completely by using one of the following techniques:

• Use o/O to start a new line from a previous line
• Use cc/S to edit the line (takes indention into consideration)
