+;; open delimiter, to a whole list from the buffer. Convenient for
+;; example when writing Lisp or TeX.
;; `try-expand-list-all-buffers' : Like `try-expand-list' but searches
;; in all buffers (except the current).
;; `try-expand-dabbrev' : works exactly as dabbrev-expand (but of
;; variable with all kinds of try-functions above, it might be an
;; idea to use `make-hippie-expand-function' to construct different
;; `hippie-expand'-like functions, with different try-lists and bound
-;; to different keys. It is also possible to make
+;; to different keys. It is also possible to make
;; `hippie-expand-try-functions-list' a buffer local variable, and
;; let it depend on the mode (by setting it in the mode-hooks).
;;
;; opposite situation to occur, that `hippie-expand' misses some
;; suggestion because it thinks it has already tried it.
