An alternative approach that may work in SOME circumstances, and please note that I said SOME circumstances, and that I swear that I will only spend 90% of your life savings on beer and lose women..............the rest I shall waste

A floppy...........yeah! one of those funny 3.5" things............has a text file on it.....a table of data.............YOUR DATA.

Use a normal data entry screen and just copy and paste.............that will stuff a keylogger, as you have not pressed any keys, and you have not selected anything from a virtual keyboord

OK, there are a hell of a lot more security issues there, but those exist anyway and this is about KEYLOGGERS per se.

As for screen captures, well that is another issue............and my method is faster so reduces the window of opportunity?
