 4. -Run the following search/replace action in TSE

     1. -Highlight that block of text

     2. -Select from menu option 'Search'

     3. -Select from list 'Replace'

     4. -Copy/paste or type the following search string
         in the 'Search for' box:


{,...................................}{.@}


         1. -That is:

              a '{'
              followed by a comma ','
              followed by 35 dots '.'
              followed by '}'
              followed by '{'
              followed by a dot '.'
              followed by a '@'
              followed by a '}'

     5. -In 'Replace with' fill in

              \1\n\2

     6. -In 'Search options' fill in

           glnx

 5. -What this regular expression thus does:

     1. -From the starting position of the cursor

         1. -It searches first for a comma

         2. -Then it searches for 35 any characters after
             that

         3. -Then it searches for 1 character more.

         4. -It takes 2. and 3. and puts a newline character
             between it, and replaces

             1. -That newline character forces TSE
                 by design to split the line at that
                 position

 5. -After the replace actions the block will look like
     this
