Keyboard with cut & paste keys on SAP

[sapy]

Is anyone using a microsoft or other UK keyboard with Copy & Paste keys? A large part of my work involves copying from spreadsheets to SAP and vica versa. After years of using Cntrl C and Cntrl P I have developed arthritis in my little finger. I now use my thumb on the Cntrl key and index finger for C or P but I am concerned this will create a problem with my thumb hence the interest in a keboard with a single button action. Unless there is a way to get SAP to accept a rght mouse click copy / paste?
