Automate keypresses

[Christian K <syphdias@xxxxxxxxx>]

Hey,

I'm trying to automate a benchmark for prompt render times with
https://github.com/romkatv/zsh-prompt-benchmark. This requires a pressed
Enter key to work.

Is there a way so simulate key presses without using something like expect?
Ideally this would also work in something like travis.

Best,
Christian
