PiRX:
Welcome to the world of K-Meleon.
There are several resources that might help you . . .
With regard to 'documentation' on Macro Language . . .
http://kmeleon.sourceforge.net/manual/macro-lang.html
With regard to 'sample' Macros that others have written (in addition to those available within the macros you already downloaded) . . .
From the Menu . . .
Help -> K-Meleon Wiki . . . then select Macros
I recommend you check the 'resources' page below for additional information . . .
http://kmeleon.sourceforge.net/resources.php
I hope this helps, and, welcome to the world of K-Meleon.
