- A dragged handle no longer snaps to its own path's bounds and centre, which move with the handle; the path's anchors are point and alignment targets instead. - Shift steps 45° from the Constrain Angle preference, like the cut and gradient tools. - snap_draw and snap_handle share one pixel/grid/smart-guides switch. - A test that a smooth anchor's opposite handle turns with a Shift-dragged handle and that Alt still breaks it, and the tools' module docs (both from #338).

//! Direct Selection (A) and Group Selection tools.
|
||
//!
|
||
//! Direct Selection: click an anchor to select it (Shift toggles), click a segment to select the
|
||
//! path's anchors on that segment, drag to move selected anchors, drag a direction handle to
|
||
//! reshape (Shift keeps it at 45° steps round its anchor, Alt moves it alone; smart guides snap
|
||
//! it), marquee to select anchors, drag a live rectangle's corner widget to round its corners.
|
||
//! Group Selection: click selects the leaf; each further click on it adds the next enclosing group.
|
||
//! Both pick the key objects of a blend. Direct Selection also edits a blend's spine: drag its
|
||
//! points (a key object on a point moves with it) and, once a point is clicked, its handles; and
|
||
//! the points of selected gradient meshes and mesh envelopes and their handles ([`MeshEdit`]).
|
||
//! Dragging a corner or an edge of area type's frame reshapes the type area (`text.reshapeArea`):
|
||
//! the text reflows at its size.
