Returns a Boolean indicating characters in cells within the specified range. Using this method doesn't change either the selection or the active cell.
The settings for LookAt, SearchOrder, MatchCase, and MatchByte are saved each time you use this method. If you don't specify values for these arguments the next time you call the method, the saved values are used. Setting these arguments changes the settings in the Find dialog box, and changing the settings in the Find dialog box changes the saved values that are used if you omit the arguments. To avoid problems, set these arguments explicitly each time that you use this method.
