Bat to send F1 keystroke after launch

[SSSTAINLESSS]

hi, im launching DolphinWX via .bat file, and I wish for it to automatically load save state wile its booting.

Can someone please help me with the code to make it send the F1 keystroke 2 or 3 seconds after dolphin begins to launch?

Thanks in advance
