Also the simple degenerate case of the user typing '{BS}', but then, so would any solution that didn't involve modifying the keystroke recorder! Well It's better than the Abottoire, but Yorkshire!	[reply] [d/l]

Actually neither my version nor yours had this error. The key issue here is that you cant just replace .{BS} with // as this allows other char sequences to "become" a {BS} element. The process of converting {BS} to a \b char and _then_ converting the .\b's resolves this issue. But you are correct that ultimately there is no way to recover what was actually _entered_ into the computer without knowing the input rules that applied at the time of entry. Basically IMO this entire task is an interesting game but ultimately a futile one from the POV of actually solving the problem.

`perl -pe's/{BS}/\b/g;1while s/(^\|.)\010//' file` Makeshifts last the longest.	[reply] [d/l]
