Here is the script in text form so you can copy+paste into a file:
^j::
Loop, 10
{
If GetKeyState("Escape")
return
; Move to "Word with Reading" field
Loop, 6
{
Send {Tab}
Sleep 100
}
Send {F2}
Sleep 100
; Move to "Sentence with Reading" field
Loop, 3
{
Send {Tab}
Sleep 100
}
Send {F2}
Sleep 100
; Move to next card
Loop, 9
{
Send +{Tab}
Sleep 100
}
Send {Down}
Sleep 100
}
return
Edit:
I just caught that I say "convert the sentence" twice in a row at the beginning of the video. In my head I was making sense lol. The first time I say it I am referring to pressing 'F2' which is the "convert sentence" button in the migaku add-on. I use that rather than 'F3' which just converts a single highlighted word, because it's faster. The second time I am referring to converting the "Sentence with Reading" field on the card using F2.
