   - With Real-time Drawing and Editing off, a dragged selection whose outline points and evaluated objects come to more than 100,000 shows its moved bounds instead, as the selection at rest does (#525, #2460; `real_time_drawing_off_draws_the_bounds_of_a_selection_too_big_to_outline`, `real_time_drawing_off_draws_the_bounds_of_a_group_too_big_to_outline`, `real_time_drawing_off_draws_the_bounds_of_a_repeat_with_too_many_objects`).
   - With Real-time Drawing and Editing off, a move or handle drag of a group, blend, envelope, repeat or intertwine draws the outline of each of its objects instead of one union of them, as VectorCraft's own rule (`real_time_drawing_off_outlines_a_dragged_group_member_by_member`, `real_time_drawing_off_outlines_a_resized_group_member_by_member`, `real_time_drawing_off_outlines_a_dragged_blend_step_by_step`, `real_time_drawing_off_outlines_a_dragged_envelope_object_by_object`). A group with a Pathfinder effect draws the area the effect makes, a gradient mesh draws its mesh lines, and a symbol instance draws its bounds (`real_time_drawing_off_outlines_a_dragged_pathfinder_group_by_its_area`, `real_time_drawing_off_outlines_each_mesh_of_a_dragged_repeat_once`, `real_time_drawing_off_outlines_a_dragged_symbol_instance_by_its_bounds`).
   - Dialogs move by dragging their heading (the band down from the top edge, as a title bar), stay on screen and keep where they were moved for the session; the form dialogs' choices are dropdowns (Offset Path's Joins, Average's and Shear's and Reflect's axis), and Offset Path lists Offset, Joins, Miter Limit and previews (#423).
-  - Dialogs open with their first field focused and its value selected: type a value and press Enter (Move, Rotate, Scale…). A dialog opened from a menu takes the keyboard focus every time it opens, not only the first (#1367), and one whose first field starts greyed out (Blend Options on Smooth Color, Layers Panel Options) gives the focus to that field once it is enabled (#1395). Number fields in panels, the Control bar and dialogs (preferences too) step with Up/Down, or with the mouse wheel over the hovered field without requiring focus (#485, #5949: a notch a step; the panel under it then stays put, and a disabled field leaves the wheel to scrolling) (Shift: ten, Ctrl/Cmd: a tenth of their unit), applied at once.

A field takes the wheel only when the pointer was moved onto it after the field last moved or was covered by a window or overlay, and the wheel stream began there; a stream that began elsewhere, such as a panel scrolled under a still pointer, stays there until 0.5 s pass with no wheel input or the pointer is pressed on a field (VectorCraft's own rule and value).
   - While Alt (Option on macOS) is held, the Flare Tool Options' Cancel button reads Reset, which puts every option back to the Flare tool's default and leaves the dialog open (`ui.dialogReset`).
   - A plain step of a number field (Up/Down or a wheel notch) goes to the next whole unit in its direction and a Ctrl/Cmd step goes to the next tenth, so 5.1 mm steps up to 6 mm and down to 5 mm (#2881). A Shift step adds or takes ten and keeps the fraction.
   - In the number, text and color fields of the panels and the Control bar, Shift+Enter (Shift+Return) applies the value and keeps the field active with its value selected; a text box of several lines takes it as a line break. In a dialog, Shift+Enter applies the value and confirms the dialog, as Enter does.

Escape and pointer departure keep the change. The field takes the wheel only when the pointer was moved onto it after the field last moved or was covered by a window or overlay, and the wheel stream began there; a stream that began elsewhere stays there until 0.5 s pass with no wheel input. This rule and its 0.5 s are VectorCraft's choices. Other font-picking menus and modifier-wheel input keep their existing behavior. |
