How to convert all text to lowercase in Vim

Question

How do you convert all text in Vim to lowercase  Is it even possible

User · Accepted Answer

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
