Hi,      I have the following code to search forward from point.      But If I have a string like SOMETHING_HERE=$(HI)      then this code yanks the whole "SOMETHING_HERE=$"      and searches for it forward. How do I limit it to      "SOMETHING_HERE". I want it to stop if it encounters      any special characters except "_" and "-".      Here is the code: (defun my-viper-search-yank-word (arg forward)   "Search forward for ARG occurance of word under point. If FORWARD is nil, searches backward instead."   (let ((viper-re-search t))     (viper-search      (concat "\\<" (regexp-quote (current-word)) "\\>") forward arg))) (defun my-viper-search-forward-yank-word (arg)   "Search forward for ARG occurance of word under point. Like the Vim command \"*\" (but not exactly)."   (interactive "P")   (my-viper-search-yank-word arg t)) Regards, Maindoor.
