It's something that compiz users certainly remember and it's also available on gnome via gnome-shell-mousewheel-zoom. Unfortunately kde doesn't allow the mousewheel to be used in a shortcut (e.g. with the alt modifier), so one has to resort to hacks like xbindkeys. Reproducible: Always

Just for the record: I already implemented this in my Wayland branches, see http://quickgit.kde.org/?p=clones%2Fkde-workspace%2Fgraesslin%2Fkde-workspace.git&a=commit&h=90e062668efd8dc321b1bf45a8c34a72403fd670 This is soon going to be merged into master, so the next version of KWin/Wayland will have this feature.
