It is documented under ":help aw" (aw, i.e. "a word" being the "motion" applied after v sets characterwise visual). «Leading or trailing white space is included, but not counted.» IOW, white space is included on one side (but not both). If Vim doesn't find white space where it looks for it first (after the word IIUC) then it looks on the other side. Best regards, Tony. -- -- You received this message from the "vim_dev" maillist.
