I meant it's difficult for the user to find the current page (that is
displayed in the image buffer) to find the corresponding page in the
text buffer (with the output from `pdftotext').

I don't mind having a command that would switch from the image buffer
to the text buffer and narrow it to the current page.  So it would be easy
to copy any text from the textual representation of the current page.
