Sending a keypress to an application

Question

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.
