I previously asked the following question on how to indent the cursor to the identation of the above line:
How to ident the cursor to the indentation of the above line?
A correct answer was provided for how to achieve this in normal mode.
I wonder if it's possible to do the same in insert mode, so that I don't first have to enter normal mode?
Currently, I only know how to use Ctrlt and Ctrld to increase and decrease indentation, respectively, in insert mode.
