This just added for the next version.
* Along with the existing control options, the following new behavior has been added:
** If you are standing still on the X axis (you _can_ be jumping or falling, in other words), then all you have to to is hold or tap upwards, then release, and you will fire in an upwards 45 degree angle until you next move on the X axis.
** If you are standing still on the X axis, and are not ducking (so you _must_ be jumping or falling, in other words), then all you have to to is hold or tap downwards, then release, and you will fire in a downwards 45 degree angle until you next move on the X axis. Even after you land.
** The idea is that this is a quick way to do angled shots while stationary without having to use the angled-shots button. Positioning yourself where you want to be, then just tapping the up key and then laying loose with a barrage of shots at an upward arc is really really easy. We didn't do it quite the same way with the downward shots (you have to be jumping/falling for this to apply) because that would have eliminated low-shots.
** This isn't an option to toggle on and off simply because it's so unobtrusive the way that it's been implemented. But if that later seems needed, we can certainly add a toggle.
