--- un/indents text; behaviour varies based on selection and un/indent.
--- * if there's a selection, it will stay static around the
---   text for both indenting and unindenting.
--- * if you are in the beginning whitespace of a line, and are indenting, the
---   cursor will insert the exactly appropriate amount of spaces, and jump the
---   cursor to the beginning of first non whitespace characters
--- * if you are not in the beginning whitespace of a line, and you indent, it
---   inserts the appropriate whitespace, as if you typed them normally.
--- * if you are unindenting, the cursor will jump to the start of the line,
---   and remove the appropriate amount of spaces (or a tab).
