Indentation-Based Motion Commands
---------------------------------
These commands, primarily for interactive use, act based on the
indentation in the text.
- Command: back-to-indentation
This command moves point to the first non-whitespace character in
the current line (which is the line in which point is located).
It returns `nil'.
- Command: backward-to-indentation arg
This command moves point backward ARG lines and then to the first
nonblank character on that line. It returns `nil'.
- Command: forward-to-indentation arg
This command moves point forward ARG lines and then to the first
nonblank character on that line. It returns `nil'.
