Vim: Indent current (blank) line and insert

Question

Say I have the current text in the buffer, where _ marks the cursor

int main(int argc, char **argv) {
    printf("Hello, world!\n");

_
}

I have indentexpr on (though a solution with cindent or autoindent will probably work, too).

How do I begin inserting so my cursor is placed at the appropriate column to follow the indention rules, i.e.:

int main(int argc, char **argv) {
    printf("Hello, world!\n");

    _
}

Currently I find myself using ddO often (or ddo at the end of the buffer), but it seems there should be a better way. Using == or even >> or v> do not seem to work because the line is blank.

Try going back into normal mode and typing S
