 Every candidate is applied from that same immutable original document, not on top of the previous candidate. A candidate's primary replacement and additional text edits are one atomic change. Other keys close the list without accepting it: plain-text completion retains ordinary typing, newline, and configured Tab insertion; snippet completion keeps its argument navigation described below. Escape returns to Normal retaining the displayed text. There is no automatic popup. Empty, unsupported, or invalid results leave the document unchanged and report a message.
 
-Cycling creates no separate undo entries. Only the final chosen edits join the existing Insert undo group; choosing Original text adds no completion edit. Undo restores that group, and dot repeats the final resolved completion edits rather than requests or intermediate candidates. The list stays inside the document text workspace, does not cover the gutter or explorer, and never takes the hardware cursor. Wheel input over it is consumed without choosing a candidate.

 Snippet candidates expand the full template immediately, including parentheses and argument defaults. The first numbered argument is highlighted; typing replaces it, then continues within that argument. Repeated occurrences of the same argument update together, without broadcasting to secondary carets. Backspace/Delete stay within the active argument; Enter can insert a newline there. **Tab** moves forward and **Shift+Tab** backward in ascending tabstop order. Replacing an enclosing argument removes its nested arguments, not adjacent independent ones. Reaching the final `$0` position ends navigation, so subsequent Tab uses the configured spaces-or-tab insertion. Escape, ordinary cursor motion, paste, commands, and focus/buffer changes also end navigation without removing the expanded text.

 ## Selections and multi-caret editing
 
-Editing uses an ordered selection set with one primary target. Cursor and word motions apply to every target; Visual motions keep each target's anchor and move its active endpoint. Whole combining sequences and ZWJ emoji remain intact. `v` selects characterwise, inclusive of endpoints; `V` selects every complete row touched by the endpoints, including blank and empty final rows. Switching between `v` and `V` retains endpoints; pressing the current shape's selector again cancels. Read-only ranges are end-exclusive. Characterwise `$`/End can select the newline after a non-final row; selected newlines appear as a blue blank cell after the line. Linewise highlighting covers the copied text, including trailing whitespace, plus one blank cell for each copied newline; unused viewport space and the gutter remain unhighlighted. The status reads VISUAL LINE. Blue highlighting overrides yellow search highlighting; secondary carets are magenta, including on empty lines and at line ends. Only the primary owns the hardware cursor and viewport. The status line counts all targets, including offscreen targets.

The status reads VISUAL LINE. Blue highlighting overrides yellow search highlighting; secondary carets follow the mode palette (magenta in Visual), including on empty lines and at line ends. The primary software cursor overlays these text colors and alone drives the viewport; its shape and mode colors are [configurable](configuration.md#preferences). The status line counts all targets, including offscreen targets.
 
 Ctrl+k/Ctrl+e clone each target to the adjacent row, preserving preferred terminal-cell columns (tabs use four-cell stops); Visual cloning preserves both endpoints. Duplicate carets and truly overlapping selections merge; adjacent ranges remain distinct. Visual Ctrl+l creates one Normal caret at the first nonblank of each touched row. Visual `I`/`A` similarly create one Insert caret per touched row at first nonblank/end. Occurrence actions use the primary selection as a literal, potentially multiline, grapheme-aligned query: Ctrl+n adds the next non-overlapping occurrence and wraps; Ctrl+s moves only the primary to that occurrence; Ctrl+a selects all occurrences.
