shifted arrow keys and the region

XEmacs 21.2 (beta42) \"Poseidon\" [Lucid] (alphaev5-dec-osf5.0) of Mon Jan 22 2001 on goedel1 I was just playing around and I discovered that if I hold the shift key down and hit the arrow keys, the mark is set and the region is activated. In fact, it acts just like I hit 'C-spc' and then the unshifted arrow keys. This seems like a fine thing to me. The complete lack of documentation is what puzzles me: if I run 'describe-key' on 'Sh-up', I get the description for 'up'. (Actually, if I hit 'C-h k', I get the prompt "Describe key: ". If I hit 'Sh-up', then I see "Sh-up" appear briefly in the minibuffer, and *then* I get the description for the 'up' key.) The description for 'up' doesn't say anything about the behavior when the shift key is held down. Similarly, if I hit 'C-h b', there are no listings for the shifted arrow keys. So: should the function describe-key give a description for 'Sh-up' (etc.)? Should the documentation for each arrow key say what happens if you hold down the shift key? Should describe-bindings have listings for the shifted arrow keys? (A cursory inspection of the info pages doesn't help much, either; for instance, these shifted arrow keystrokes are not given in the "Setting the Mark" node.) -- John H.
