Replace Keys is a free and friendly, although somewhat annoying, joke to spend your friends, family or co-workers.
The objective of Replace Keys is to drive the user who is working at the computer crazy, because it changes the letters of the texts that the user is writing. The program does not change them immediately, as they are written, but after a while, which makes it even more mosqueante.
The time, in seconds, that elapses since the user writes the word and Replace Keys exchanges the letters for others, is specified by the person who wants to play the joke.
You can free download Replace Keys 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
