Feature request: smart movement key interpretation

[Zababa]

I play Angabnd 3.1.1.1626 on a laptop (Win XP) with no numpad, which troubles me a lot. Luckily, I have found, that I can define a keypress delay, so that when I press two arrow keys (almost) simultaneously, @ moves into the resulting direction, e.g. right-arrow pressed with up-arrow has the same effect like the 9 on numpad. Forced to play on the four arrow keys I noticed one drawback which annoys me:

Because I almost never move by pressing the arrow keys alone but mostly hold Shift to them, @ keeps moving in the desired direction (intelligently crawling through corridors) as long as there is nothing disturbing (e.g. a monster, hunger, etc.) or there is but one choice of a progress direction. But this shift-aided movement works only for the four basic directions (left, right, up, down). Whenever I would like to start a shift-aided movement in one of the diagonal directions (by pressing two arrow keys simultaneously) it does not work. When I play on a external keyboard, pressing shift Num9 works exactly as would like shift up+right to work. But as for now I just can't move @ diagonally with shift pressed. Moving without shift I feel very unsafe, especially when I have to crawl through the chequered vaults or earthquake zones.

So my request is:

1. enable shift-aided diagonal movement when playing with the four basic arrow keys and keypress delay.
