This is a group of Keyboard Maestro macros to move windows in a way inspired by Windows snap move shortcuts.
The snap move macros have the same logic in the four different directions.
If the window moves along the directory, the side which first hit the screen boundary is named as near side, and the opposite side is the far side. For example, in the macro "Window Snap Right Ctrl + Option + Left", the right window side is the near side, and the left is the far side.
- (1) If the near side does not near the screen boundary, move the near side along the direction until it meets the screen boundary.
