column-selection

Create multiple selections across lines by dragging. Enables column/block selection with carets on each line for efficient multi-line editing.

Features

• Drag selection: Hold modifier key and drag to select a column of text.
• Sticky mode: Toggle persistent column selection using command or left-click status bar item
• Picker mode: Select region with two clicks using command or right-click status bar item.
• Edge scrolling: Auto-scroll when dragging near editor edges.
• Status indicator: Shows current mode in the status bar.
• Precise positioning: Temporarily disables atomic soft tabs during selection for accurate column alignment.
• High performance: Reuses existing selections and uses mergeIntersectingSelections for efficient updates, avoiding costly recreation of selection objects during drag.
• Inline blocks support: Works correctly with inline block decorations (e.g., hydrogen-next output results).
• cursor-leader compatibility: Works correctly alongside cursor-leader, including when power mode is active.

Note: For the best column selection experience, consider disabling atomic soft tabs globally in Settings > Editor > Atomic Soft Tabs. This prevents cursor snapping to tab boundaries and allows precise positioning at any column.
