How to link multiple key events in AppleScript? I have been trying to write an AppleScript that would open the mail app register a save as key event (Shift+Command+S) wait 1.5 seconds, do a return key event ("Enter") and then wait another 1 second and then register a down arrow key event.

activate application "Mail"
repeat 2310 times
    tell application "System Events" to keystroke "s" using {shift down,command down}
    delay 1.5
    tell application "System Events" to keystroke "return"
    delay 1
    tell application "System Events" to keystroke "DownArrow"
end repeat
tell application "System Events" to repeat 2310 times
    tell application process "Mail" to set frontmost to true
    keystroke "s" using {shift down, command down}
    delay 1.5
    keystroke return
    delay 1
    key code 125
end repeat
