Ah I see. So IIUC Vim's fuzzy matching will match (caselessly) if there is an extra letter but not if there is a missing letter, and it won't match swapped letters: if the search string is 'word', then Vim will find 'WoRd' or 'worrd' but not 'wrd' or 'wrod'. Thanks for explaining. Best regards, Tony. -- -- You received this message from the "vim_use" maillist. Do not top-post! Type your reply below the text you are replying to.
