Suppress all empty lines
Find: "^\n" (without quotes)
Replace: "" (without quotes)
RegExp
Note: You may have to repeat it several times to remove all empty lines (until the editor can't find the string to replace), because only the first one of a series of consecutive empty lines will be edited.

Find: "^.+$" (without quotes)
Replace: "" (without quotes)
RegExp
Comment out lines
Find: "^" (without quotes)

Comment lines
Find: "$" (without quotes)
Replace: " // Comment here" (without quotes)
RegExp
Note: Empty lines will not be affected. This example actually adds a text at the end of every non empty line, the comment symbol used ("//") is the one of PHP.

(Only the second instance of "(`phone`,`phonecell`,`fax`)" must be selected and search and replace must be applied to such selection).
Note: this is meant to replicate the values in a INSERT query according to the specified fields (and use the empty values as a placeholder): you simply need to copy the fields and past them after VALUES, and then replace them this way.
