Hi Sheng, you can do this interactively in "Editing Mode". Choose "Mouse > 3 Button Editing" from the menu or click the lower-right panel in the main window.
In Editing Mode, you can pick single atoms into named selections (pk1, pk2, ...). So for your peptide bond, pick the N and the C, type "fuse" and hit enter. To adjust the torsion angle, you can CTRL+Drag with the left mouse button. If you want to fuse non-interactively (using a script), you can select the endpoint atoms using PyMOL's powerful selection language: PyMOL> fuse last (obj01 and name C), first (obj02 and name N) Hope that helps.
