I am trying to copy and paste in a Toshiba Satellite laptop using the touch pad. Everytime I have to select the text and right click -> select copy and then right click again -> select paste.

I was wondering if I could select the text and then just right click to paste it. This happens when I use a USB mouse but not with the touchpad. How can I enable this feature for my touchpad in KDE?

Usually you get that "select -> paste" functionality by selecting then clicking the middle mouse button (that is, mouse button 2). If you turn on "Emulate3Buttons" (I believe that's right, if not then it's called something very similar) in your X server configuration then you should be able to do it by clicking both the touchpad buttons simultaneously.

Note also that the above will apply to any X environment, not just KDE; so maybe it's not what you're looking for after all. I only use FVWM2 and hence don't know much about big fancy desktop environments.
