From the developer:
TwoUp is similar to "tiled windows" functionality available on other operating systems. TwoUp consists of four actions which can be performed on the frontmost application window:
Left (move window to fill the left half of the screen)
Right (move window to fill the right half of the screen)
Up (move window to fill the top half of the screen)
Down (move window to fill the bottom half of the screen) These actions can be triggered via the TwoUp menu in the Mac menu bar or via system wide shortcuts.
