There's a new selection-box on the header of the action editor, which sets the mode of auto-snapping for transforms. By default auto-snapping is off. There are 3 modes of auto-snap: * Off - transforms per normal * Frame Step - grid-step transform (may have errors with scaled actions) * Nearest Frame - true snap-to-frame (takes into account nla-scaling) These translate to the following hotkeys when transforming: * Off - no keys press/held (as it's always been) * Frame Step - Ctrl (as it's always been) * Nearest Frame - Shift (replaces old shift-key behaviour which was not useful)
