I would think
Code:
/pause 300, /doa 5
/pause 700, /autoinventory
/pause 300, /doa 5
/pause 700, /autoinventory
/say Restart Forage Now
The pauses happen after the action on their same line.
Still only 2 forages but with this you don't have to do any manual inventory and can restart the hotkey as soon as the say goes out (and presumably triggers an audio alert through your log parser).
