Snapping to the grid
When snapping is enabled, you can also choose to have elements in the timeline snap to the vertical grid lines in the timeline.
From the Options menu, choose Snap to Grid (or press Ctrl+F8) to toggle snapping to grid lines.
Snapping to markers
When snapping is enabled, you can also choose to have elements in the timeline snap to markers in the timeline.
From the Options menu, choose Snap to Markers (or press Shift+F8) to toggle snapping for all marker types:
•Markers
•Regions
•CD track regions
• CD index markers
• Command markers
If the Event Media Markers command is selected on the View menu, you can also use media markers as snap points when you click
in an event or edge-trim an event. For more information, see Editing events on page 78.
Snapping to events on other tracks
When snapping is enabled, you can also choose to have elements in the timeline snap to the ends of events on other tracks.
From the Options menu, choose Snap to All Events (or press Ctrl+Shift+F8) to toggle snapping to event edges across tracks.
Quantizing to frames
From the Options menu, choose Quantize to Frames to force edits to occur on project frame boundaries. This setting is
independent of grid and marker snapping.
When Quantize to Frames is turned on, the following actions will always occur on frame boundaries:
• Positioning the cursor
• Making selections
• Placing markers and regions
• Moving video events
Tip: To change the spacing of the grid, choose Grid Spacing from the Options menu and choose a setting from the submenu.
Note: If a media file’s frame rate does not match your project frame rate, you will not be able to snap to media markers (or other
snap points that do not occur on a frame boundary) when Quantize to Frames is selected on the Options menu.
Note: If Quantize to Frames is on while dragging an audio event and the selection group contains video, the movement is
quantized so the first video event is quantized (instead of the audio event).
When performing audio-only edits, quantization will occur only if Quantize to Frames is turned on and the Do not quantize to
frames for audio-only edits check box on the Editing tab of the Preferences window is not selected.

Editing tab on page 429.
