Let\'s say I have string \"The quick brown fox jumps over the lazy dog\" can I change this to \"The slow brown fox jumps over the energetic dog\" with one regular expression
You can concatenate vim substitutions:
The quick brown fox ran quickly next to the lazy brook.
:s/quick/slow/|s/lazy/energetic/
The slow brown fox ran quickly next to the energetic brook.
The advantage here is that you have to type your substitutions just once
