问题
Is there an easy way to make an application think the user has pressed a key?
Here's why I am trying to do this:
I am trying to track down a regression in a Wine application. The bug only seems to show itself when the user presses a specific key (in this case, escape). So I wanted to give git bisect a script that launches the application, simulates pressing escape, and tells git that that the revision is bad if the program crashes.

Use xdotool: http://www.semicomplete.com/projects/xdotool/

There is some sample code at: http://www.doctort.org/adam/nerd-notes/x11-fake-keypress-event.html
It might be roughly what you need. Also read the comments (there is a sample for selecting a window in a different way).
