vim tips and tricks

reformatting

These are useful to reformat text paragraphs or chunks of code:

    V=  - select text, then reformat with =
    =   - will correct alignment of code
    ==  - one line; 
    gq  - reformat paragraph

Options to change how automatic formatting is done:

    :set formatoptions (default "tcq")
        t - textwidth
        c - comments (plus leader -- see :help comments)
        q - allogw 'gq' to work
        n - numbered lists
        2 - keep second line indent
        1 - single letter words on next line
        r - (in mail) comment leader after
