Indentation

M-m (which is bound to back-to-indentation) moves the point to the first nonblank character following the indentation at the beginning of the line. C-j (which is bound to newline-and-indent) inserts a newline and then indents. M-C-o (which is bound to split-line) the text following the point is put on a newline with enough indentation so that its first nonblank character is on the same column as the point. Tab and C-i (which are bound to indent-for-tab-command) indents the current line in a major mode specific way. These work the same was as GNU Emacs, except that major mode specific indentation is not currently supported very well.

M-x auto-indent-mode will toggle on and off auto indent mode. When auto indent mode is on anything which inserts a newline, including Enter and fill-paragraph will indent the newline the same as the previous line. This is different than GNU Emacs.
