Verbose and not worth the read IMHO. The best tip in this entire document was changing a sentence to title case. >Select the text you want to convert, hit :, then enter the regex: s/\<\(\w\)\(\w*\)\>/\u\1\L\2/g. And, even this is not completely correct. The expression will not work if you select part of a line. Your best bet would be to remap the following: nnoremap <A-c> :s/\<\(\w\)\(\w*\)\>/\u\1\L\2/g<CR> vnoremap <A-c> :s/\%V\(\w\)\(\w*\)\%V/\u\1\L\2/g<CR> To get key bindings that you like (I've defaulted to the EMacs capitalize-word binding).
