As far as I can tell, that reference to '--' in the man page
is an error, there is no such option.
I'm having trouble understanding the second sentence so I can't be sure
if '--' is a typo for '-'.
I checked the source, fvwm/bindings.c.
Unless it's very well hidden, it doesn't parse anything like '--'.
The closest it gets is:
if (
action == NULL || *action == 0 ||
(action[0] == '-' && !is_pass_through))
{
is_unbind_request = True;
}
Basically, it sees the first character of the next action
and turns on is_unbind_request. So, if the arg was
'--' it would still do the unbind.

I'm not quite sure what is going on then. When I run PrintInfo Bindings I do not see a binding show up when I use the -- option (unsure why this is not showing up). So unsure if the -- binding is not being listed correctly or not. It could be I'm overlooking something with the pass through option I do know that this really isn't the best way to do things, in general most applications will not like this. From the man page Note that Fvwm actually intercepts all events for a window-specific binding and (if the focused window doesn't match any of the bindings) sends a synthetic copy of the event to the window. This should be transparent to most applications, however (for security reasons) some programs ignore these synthetic events. Really most programs ignore these synthetic events (see FakeKeyPress) so I would think of another way to achieve your goal. Though if mpv accepts synthetic events, you could try FakeKeyPress over a pass through --, and see if that works for you. My suggestion is find another way to achieve your goal. Some suggestions: *) Use a modifier on Up/Down that isn't also used by MPV for your bindings. *) Write a function and bind it to a binding that enables/disables these scroll bindings. Not ideal, but this way you could disable the bindings when you wanted to use Meta-Up inside of mpv. You could even use Schedule to make it so the bindings will automatically enable them selves after a set period of time. jaimos

Yes, I read about the application to accept the pass through. But with exact that setting, it does scroll inside the window too; so I don't think that any event for the application is generated at all.

This is only a valid action for window-specific bindings. So in conclusion, when using window specific bindings and you want to propagate the press to the window you want to use '--', not '-' (which tells fvwm to remove the binding). Thus I think you should be able to get this to work if you change your bindings to Key Up A M Scroll +0 -10 Key (mpv) Up A M-- jaimos

-BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hi folks, I use version 2.6.8 in debian. - From the documentation, the following mapping: Key Up A M Scroll +0 -10 Key (mpv) Up A M - Should bind alt-Up to the Scroll except in mpv window. But it also scrolls in mpv windown. So I played a bit around. When I do the scroll mapping as above but from command line I do `FvwmCommand 'Key (mpv) Up A M -'`, it does not work. So I tried `Key (mpv) Up A M Echo Up` which worked and echos the Up. When I do `Key (mpv) Up A M -` afterwards via FvwmCommand, it does as expected and mpv get the Up key press. This works reliable so I decided to put that exact sequence in config file: Key Up A M Scroll +0 -10 Key (mpv) Up A M Echo Up Key (mpv) Up A M - But then it does not work and only the scroll mapping is done. So: - - Is that a known bug? - - How to do a mapping for everything except in mpv window? - - What is the difference between `-` and `--` in this context?
