But the things running inside the xterm (iTerm2) terminal emulation can only receive text input, for example ANSI Esc sequences (or codes). It looks as if these codes are produced by the given "mouse events":

It's not that simple if you have the mouse-wheel-follows-focus set,
because it also keeps track of the cursor location.  Here's an example
