Grab the latest beta and look inside the __init__.py. Near the beginning you find a list like:
Code:
ACTIONS = (
("TogglePlay", "Toggle Play", "Simulate a press on the play / pause button.", 18808),
("Stop", "Stop", "Simulate a press on the stop button.", 18809),
("PreviousTrack", "Previous Track", "Simulate a press on the previous track button.", 18810),
...
Every line consists of four items:
1. The Python identifier to use. This should be a short descriptive camel-cased word without spaces.
2. The name of the action, as it is shown to the user. Here you can use spaces and punctuation marks.
3. The description of the action as a full sentence. If you don't want to supply a description, use "None" (without quotes) instead of a quoted string. Example:
Code:
("ToggleRepeat", "Toggle Repeat", None, 18843),
4. The parameter as an integer number, as you find it in the .rc-file.
Just add more lines and the plugin will turn them into actions. Be careful to stay with the right indentation.
Seems like there is no fast rewind function in WMP. Only a "rewind" function. I have fixed the source to use 18812 now, but haven't tested it.
