ROFL puzzle

1) Start with the acronym ROFL.

2) Add another letter and unscramble to create one of the words that the acronym stands for.

3) Now subtract one letter and reverse the word to create something that means the opposite of word #2.

4) Now replace the last letter with another letter to get something in between #2 and #3.

5) Now reverse that word and replace the first letter with another letter to find how to get out.
