how do you use tabs in "Find and Replace" system?

The find & replace does not seem to accept tabs. How do I do a mass replacement of a chunk of text with a set of tabs?

You need to use regular expressions. Open the full search&replace tool (Ctrl H) → More options → check Regular expressions. Now you can use the expression

\t

to represent a tab stop on both boxes: search and replace.

NOTE: this works on 5.4, but if my memory does not fail me, on earlier versions there was a bug that causes the expression \t to fail on the replace box, but as I said now it works without problems.

In Version 6.4.3.2 (x64) for Windows 10, when clicking Ctlr H is “Other options” (not “More options”)
I check-marked “Regular expressions”
Typing /t in the Find field does not find any tabs.
Going to “Attributes” and clicking “Tab stops” also does not find any tabs.
Does searching for tabs no longer work?

@oconomowoc: look at the distinction between \t as in the answer, and /t as in your comment.

Thanks! A silly mistake. Should I delete my post?
