• Go to Start > Settings > Control Panel > Accesibility Options
  
  Select the mouse tab
  Check the box writen as "use mouse keys"
  Apply > Ok
  
  (or simply press Shift+Alt+NumLock to turn on the mouse option)
  
  Now u can use your neumeric keys (2, 4, 6, 8) instead of the mouse
  
  To highlight the text in this way, first press the zero key
  Then u can move your cursor using the neumeric keys to highlight your text
  
  Then ofcourse u know Ctrl+C to copy and Ctrl+P to paste
  
  Good luck
