Tried copy paste on the redacted blocks, nothing there of course. "GSA" pastes as ctrl-], (, and a character that deletes the line and returns the cursor to the beginning, probably ctrl-W.

So it might not even be possible to enter the characters for "GSA" into the ctrl-f window, to search for that. Counting backward 17 from A should give "0", zero, so that might've been done on purpose?
