1. Select the few lines and press F9 ("Evaluate Selection" - also from the menu)
2. Check out Cell Mode

One way is to use "cell mode". Put the characters "%%" (without quotes) on the lines above and below the section you want to run. Put the cursor in that section, and it will be highlighted. You can then run just that section.
