I want to use the Tab key to indent a block of text and Shift-Tab

key to unindent a block of text. How do I map the keys to do this? This behavior is similar to textpad, visual studio, etc. Use the following mapping:

    :inoremap  

    :nnoremap  >>

    :nnoremap  

    :vnoremap  >

    :vnoremap  

Note, that the <S-Tab> mapping will work only if Vim receives the correct key sequence. This is mostly the case with GUI Vim.
