If you don't have to manually select which lines should be de-dented,
you can also use

:%le

which uses the :left command to remove all leading space. It works
with any range

:10,20le

or the visual selection

:'<,'>le

or with matching lines:

:g/pattern/le

You can read more at

:help :left

(there's also a ":center" and a ":right" that use the 'textwidth'
setting if you want those)

Alternatively, you can select a range with visual mode and use the
"<" command with a ridiculously large prefix-count like "99<" to
dedent the selected rows by 99 levels of 'shiftwidth'

:help <

Hope these help,
