Is this possible or have I just missed another gem?
Highlight a section of code and mark as a BLOCK. This would allow global regex changes to the block only. This would, for instance, allow a contiguous section of code to have all <p> tags changed to <div> without bothering any code outside of the block. Many other uses also.
This would simplify the formatting of poetry, letters, and other quotes.
I admit that this will primarily be for Kindle display.
