A library for handling keyboard input.
I'm not sure if it's a BYOND bug or a missing feature of the library, but when I'm moving around and hold shift or ctrl, sometimes I just stop moving.
I don't think the library handles any keys in a special way, so that might be a BYOND bug or just some keyboard quirk. Does this happen in any of the sidescroller or pixel movement library demos? That'd be an easy way for me to test it.

I'm having trouble finding a Pixel Movement demo in which this doesn't happen. Watching the debug statpanel, I see the directions I'm holding. When I press Shift, Ctrl, or Alt, one of the directions disappears.

However, the Pixel Movement Demo (the fancy one) doesn't have this problem.
That could be a BYOND bug then. The pixel movement lib macros all keys, the fancy demo doesn't. Maybe BYOND is pre-empting other keys with ctrl and alt because they're used as modifiers.
