I want to be able to parse each line of text on input checking for keywords and coloring them. I already have coloring capabilities on load when I first load the file. That code is the following: 
   my $browse = $t->getOpenFile(-title => "Browse For A File!");
   if ($browse) {
      $t->delete("1.0", "end");
      $status->delete("1.0", "end");
      if (!open(TARGET, "$browse")) {
         $info = "Error!";
         $status->insert("end", "ERROR: Could not open $browse\n"); 
         return; 
      }
      $line_count = 1;
      $filename = $browse;
      my @ext = split(/\./, $filename);
      my $ext = "\." . $ext[1];

      $info = "Loading file '$filename'...";
      while (<TARGET>) {
         #$t->insert("end", "$line_count ");
         $t->insert("end", $_);

         if ($ext eq ".pl") {
            if ($_ =~ /\#/) {
               my @comment = split(//, $_);
               my $i = 0;
               foreach my $comment (@comment) {
                  my $range = length($_);
                  if ($comment eq "#") {
                     my $offset = "$line_count\.$i";
                     my $end = "$line_count\.$range";
                     $t->tagAdd("orange", $offset, $end);
                  }else{
                     $i++;
                  }
               }
            }
         }
         $line_count++;
      }
   }

I also have the same code for when a file is saved, to update the new text. I would like to able to color the text as it is input though. Would this be possible? Would any of the existing code to color commented string be of any help in doing so? I know of a way I can color the code by splitting the string on each character input but do not know how to monitor the textbox for character input. Any ideas?
