Hello, @angela-davis
Assuming there is NO condition on the choice of lines, this following regex S/R swaps, for instance, the next 2 lines till the final block of two lines of the current file
SEARCH (?-s)^(.*\R)(.+\R)
REPLACE \2\1
So, given the sample text, below, with the cursor located before the string 1A :
1A This is a 1B simple text 2A in order to 2B understand 3A how the 3B text changesYou should get :
1B simple text 1A This is a 2B understand 2A in order to 3B text changes 3A how theBest regards,
