7.2.3.2 Other indentation tricks
Whenever you are using indentation, you can use M-m (for back-to-indentation) to move to the first nonblank character on a line. On a line that's not indented, this command simply moves you to the beginning of the line. In other words, M-m brings you to the "logical" beginning of the line, which is what you usually mean when you type C-a.
Another indentation command is C-M-o (for split-line). You can use this command to create a stairstep effect. Move the cursor to the text that you want to put on the next line and press C-M-o. Note that there must be some text following the cursor in order for this command to work properly; if you try it at the end of a line, it does nothing.
Initial state:
We want to split this line.
Type: C-M-o
C-M-o splits the line at the cursor position.
