I hate how xterm scrolls half a page at a time when I press Shift+PgUp or Shift+PgDn, rather than a full page. It's so confusing and disorienting and stupid.

Is there a way to change this behavior and make it scroll a full page (or better yet, a full page less one line) at a time? I know there's a manpage, but it's tl;dr and I wasn't able to find anything relevant by searching it.
