I'd like to recenter a buffer, called "Lense", where I've inserted some text. I wished to make it the current buffer by "(set-buffer "Lense")", then "(recenter 0))". By the following code segments:

(save-excursion (set-buffer "Lense") (recenter 0))

However, it seems that the above code would only recenter the buffer which is the current buffer, and "(set-buffer "Lense")" has no effect to make the current buffer to be "Lense".

Please help me to figure out the right way to recenter the named buffer "Lense".

Thanks,

Yu
