Hi, when i do search in my Entrybox the list lowers down to that typed item
the code of which i wrote in the update_list function. how should i get
listbox items back again after it has been lowered? and another question:
if i want to format some specific text in my Text widget i should use
BeautifulSoup or can i do that with add_tag method? i used add_tag method
in my enter_meaning function but it formats the first 4 letters of anyword,
but i want the words which are in the listofwords to be formatted.
