Press "z"

[Edek11]

Hello friends. I am writing to you because I have no idea how to write it.
could you help write a script that would press the "Z" key on the in-game keyboard?
how should I do this, any tips?

I want it to be in "sendmessage / postmessage" because I want to use the computer normally while the script is running

Have a nice day
Edek
