Last change on this file since 2ec737f was 2ec737f, checked in by David Benjamin <davidben@mit.edu>, 11 years ago
Add owl_function_set_search Instead of allowing OWL_DIRECTION_NONE in owl_function_search_start, make the setsearch command just call a more approriately named function. Also, move the mainwin redisplay into owl_global_set_search_re. Although, really it should just emit a signal.
