G'Day and thanks in advance, New to KDE (currently using Linux Mint KDE) after intallation I moved (copy then pasted) some files from one folder to another on a different drive. When I moved the wheel on the mouse all the files (icons I think) I seleceted were displayed on the Desktop. Having a fiddle I found you could chane the acgion for the left Botton Right Button and the Wheel. The only thing now is I do not know how I achieved this. Could the Forum Staff point me in the right direction so I do not repeat my action of all the files Ihave selected. I would like to program the Wheel to change the Virtual Desktop (currently four). Thanks TopEnder

cashew (upper right corner) -> default desktop settings -> mouse actions -> add action -> move wheel over "input here" button (should now be vertical scroll) -> change "application launcher" to "switch activity"
