Enter or Return Key

If I have to enter a System Message, how do I tell AppleScript to press the “Return” key?

It should be something like:

tell application "System Events"
	keystroke return
end tell

Big THANKS in advance!

That’s it exactly, august. Remember that, for a keystroke command to work as intended, the target application process must be activated/frontmost:

tell application "System Events"
	set process "Target"'s frontmost to true (* insert name of the actual target process *)
	keystroke return
end tell
