Usually Vu  or VU for uppercase  is enough to turn the whole line into lowercase as V already selects the whole line to apply the action against   Tilda     changes the case of the individual letter  resulting in camel case or the similar   It is really great how Vim has many many different modes to deal with various occasions and how those modes are neatly organized   For instance  v - the true visual mode  and the related V - visual line  and Ctrl Q - visual block modes  what allows you to select blocks  a great feature some other advanced editors also offer usually by holding the Alt key and selecting the text

If you really mean small caps  then no  that is not possible     just as it isn   t possible to convert text to bold or italic in any text editor  as opposed to word processor   If you want to convert text to lowercase  create a visual block and press u  or U to convert to uppercase   Tilde     in command mode reverses case of the character under the cursor  If you want to see all text in Vim in small caps  you might want to look at the guifont option  or type  set guifont   if your Vim flavour supports GUI font chooser
