I have several questions that I hope someone on the net can help me with: (1) What is the difference between set-window-buffer and switch-to-buffer ? (2) What is the difference between set-buffer and switch-to-buffer? (3) If you a LISP program to place the cursor into a particular buffer at a specific position, and remain there for the user to see HOW SHOULD YOU DO IT? I currently do this, is this correct?

Note, though, that when it comes time to get more keyboard input, the buffer displayed in the selected window becomes the current buffer, regardless of previous set-buffers. As the documentation for switch-to-buffer states, this makes set-buffer the thing to use to work on another buffer temporarily within a lisp function, since when the function returns the current buffer will be restored to the buffer associated with the selected window (which probably hasn't changed :-). save-excursion is also handy for doing this. >(3) If you a LISP program to place the cursor into a particular buffer > at a specific position, and remain there for the user to see HOW > SHOULD YOU DO IT? > I currently do this, is this correct? > (pop-to-buffer buf-that-I-want-user-to-be-in) > (goto-char position-where-i-want-cursor-to-be) That is correct, so long as you want to use pop-to-buffer and not switch-to-buffer, which would also work. Things like find-file-other-window can also switch buffers/windows on you. -- Tom May uw-nsr!uw-warp!tom@beaver.cs.washington.edu uw-beaver!uw-nsr!uw-warp!tom
