I'm no expert, but here goes:
Code:
macro = predef:LEFT
macro = predef:DOWN
That is using the new Predefinded keys Zorlac has included in his TB 1.0.1 version. So, hope you have that version.
The Sendkeys syntax is the way that uses the { } braces. Sendkeys is good for most normal key combinations like A-Z(a-z); 0-9 (top of keyboard); F1 - F12, ect... Just look in the Sendkeys help file. It is not good to use it for Numpad keys.
For Numpad keys, try to use Zorlac's new Predefinded keys. The Numpad keys just work weird, so you have to use a different method to get them to work. Zorlac first added the RawKeys syntax to handle these. But has made it simpiler for use by creating his own Predefined syntax that sends the RawKey equivilantes for us.
Hope this helps.
