How can indent/dedent in vim without losing selection?

Question

It is really annoying, especially when I need to indent more than one level.

Answer 1

The following mappings will re-select the visual selection:

:vnoremap > >gv
:vnoremap < <gv

Note that you can also provide a [count] to de-/indent multiple levels at once.

Answer 2

You can repeat the last un/indent like other changes with the single-repeat command, the dot .. The repeated command spans the same region as before.
