If I copy from an external editor to Mathematica notebook a block of lines (with a code)
line 1 line 2 ... line n
then whole text is copied to a single cell.
I can now use
n-1 times "Divide cell" and manually create
n new cells for each line. If
n is big, then this is a hard work.
Exists some better method how do it ? For example before copying insert some special characters into text (representing an end of cell) ?
