Indenting a bunch of lines in Vim

Question

Is there a way to indent a selection of lines in Vim, like we have in text editors where we select a bunch of lines and press tab (or shift tab) to indent/unindent the selec

Answer 1

I use the following mappings to indent/unindent:

vmap  >gv
vmap  

Use TAB to indent and shift-TAB to unindent the visually selected lines.

If a block is selected Vim indents/unindents what is right of the start of the block.
