vim: undo newline in insert mode?

Question

I often accidentally press return while typing in insert mode. To undo the accidental return, I typically press backspace several times. First to remove all the automatic indentation, and then, finally, to remove the newline.

Is there a better way. Something along the lines of undoing the effect of the last keystroke?

Answer 1

In the exact same situation, I do <C-w><C-w>. <C-w> is a great asset to have in insert mode.
