I have a workaround. It will map Super+mouse scroll to the default kde zoom in/out "meta+=/-"
first we need to install xautomation and xbindkeys
Atl-F2
Code:
kpackagekit --install-package-name xautomation --install-package-name xbindkeys
create/edit a file called ~/.xbindkeysrc
this can be done with:
Alt+F2
Code:
kate ~/.xbindkeysrc
Code:
"xte 'keydown Super_R' 'key equal'"
Mod4 + Super_L + b:4
"xte 'keydown Super_R' 'key minus'"
Mod4 + Super_L + b:5
"xte 'keydown Super_R' 'key 0'"
Mod4 + Super_L + b:2
that last block is optional it bind the middle button to zoom reset "meta+0".
the b:# is the mouse number and it corresponds with xev output.
Start xbindkeys with the config we just made:
Alt+F2
now to make it start xbindkeys every time KDE starts we will create a static link to xbindkeys in the KDE Autostart folder in our home directory.
Alt+F2
Code:
ln -s /usr/bin/xbindkeys ~/.kde/Autostart/xbindkeys
