What:
* Provide Search with the "Mark All" feature.
* Mark, with a "flag", all lines where there is 'STRING LITERALS' (like this)
Why:
These days I'm revising & improving codes written by monkeys who have no idea
about "code beautification", coding standards etc.
So often codes are in Mixed Cases or CAPITAL where I want just lower case.
This requested feature can help one better avoid accidentally changing the cases of string literals.
