hi,

The following code is the find function part of your code but with part of the solution
it now prints the index (location) of the begining of a string or letter but i havn't a clue how to highlight text.

 Help with Code Tags 
 Python Syntax (Toggle Plain Text) 
def find():
    findStr = tkSimpleDialog.askstring("Find", "Find:") # Prompts user to enter a string, if nothing is entered, function returns None
    if findStr: # Test to see if the function returned a string or None
        print findStr
        start = 1.0
        while 1:
            position = text.search(findStr, start, stopindex=END)
            if not position:
                break
            print "string was found at ", position
            start = position + "+1c"
    else:
        print 'nothing was entered'
def find():
    findStr = tkSimpleDialog.askstring("Find", "Find:") # Prompts user to enter a string, if nothing is entered, function returns None
    if findStr: # Test to see if the function returned a string or None
        print findStr
        start = 1.0
        while 1:
            position = text.search(findStr, start, stopindex=END)
            if not position:
                break
            print "string was found at ", position
            start = position + "+1c"
    else:
        print 'nothing was entered'

the text widget uses index's, 1.0 would mean the first row (1) and the first column (0)
just picture the text widget as a grid, with one character in each square

so when you enter a string to search, it returns either nothing (if nothing was found) or the index for the first character in the string.

at the end of the while loop, the "+1c" means +1 column.
