In Windows, I use the X-Mouse utility to remap my mouse thumb buttons. I have one assigned as copy, and the other as paste.
In KDE, I was happy to discover that I don't need a separate utility to assign one of my thumb buttons as paste. In fact the middle (mouse-wheel) button is already assigned as Paste by default (OpenSUSE 11.3 if not elsewhere). And there's a desktop settings dialog with a "Mouse Actions" section that allows me to configure these.
The trouble is, there's only 6 possible actions for each button - and copy isn't one of them.
The info for each mouse action suggests that these are pluggable components - but I don't know how to find/install extra ones.
Is it possible to get an extra "copy" mouse action and, if so, how?
