Can't get MovementHotkey to work

[Rekuet]

Thanks for the reply.
If you read the third paragraph of my first message, you can see that the first code I tried, is just as the one you're suggesting:
<Label Char1 Local SendWin Notepad>
<MovementHotkey D>
<SendLabel Char1>
<Key J>
But for some reason is not working.

I understand that this is intended for holding down a key and being able to move a character continuously while the key is pressed and that's just what I'm trying to do.
But since I wasn't able to do it in the game, I tried to figure out how it works on a simple notepad. And in a simple notepad, holding down a key should translate into typing that key multiple times.
I understand that MovementHotkey and KeyDown will not send infinite single keystrokes but will keep a key pressed.

Anyway, the code is not working for me, it is as if I just press the key one time, it's not holding down the key.
What can I do?
