- Ardour's editor utilizes a <dfn>grid</dfn> to assist in the placement of regions
- on the timeline, or with editing functions that need to happen at a specific
- point in time. This <dfn>snapping</dfn> of the cursor and various objects to the
- grid can be toggled on or off, as does its behaviour, and grid units.
+“Snap” will cause drags and other mouse-driven operations to jump to
+positions determined by the nearest snap setting. Snap can be set to
+multiple options: markers, region start/ends, and the grid (those
+are all enabled by default. change them in prefs).
+</p>
+<p>
+Grid can be enabled, and it will draw lines at selected intervals;
+which can be musical, like 16th notes, or can be timecode based
+(minutes and seconds). You can leave the Grid enabled, but snap
+disabled, if you just want to see the lines but not snap to them.
+</p>
+<p>
+For example: if the Grid is set to “beats” and Snap-to-grid is
+enabled, then any operations such as split, paste, or range-select
+will happen exactly on a beat, according to the musical timeline and
+tempo.
+</p>
+<p>
+Alternatively, you can leave “Snap” enabled (so your mouse actions
+can snap to Markers, or region edges) but disable the Grid.

+<h2>A Warning, of sorts</h2>
+
+<p class="warning">
+The grid consist of lines running vertically in the edit canvas. If
+you zoom too far out, you might see a coarser grid than you
+expect. Ardour tries not to show “too many” or “too few” grid lines
+depending on the zoom level. You might find that items snap in-between
+the grid lines sometimes. That’s expected behavior. If you can’t see
+or snap to the grid you’d like to use, you may have to zoom in or out.
