The documentation for SnapAttraction in the manpage for 2.5.24 seems to
be missing many parts that were in the 2.5.23 manpage. I guess someone
updated the command to say is is deprecated but forgot to actually move
the documentation to the style-section.
As the documentation says
SnapAttraction [proximity [behaviour] [Screen]]
Specifying 'Style * SnapAttract 15 Screen' should work, but fvwm
seems to ignore Screen in that case. It works fine with '15 All Screen'
though, so i guess the documentation is missing a pair of []
SnapAttraction [proximity [[behaviour] [Screen]]]
