Right-click grid context menu

What it does

Right-clicking a cell (or the current selection) anywhere in the grid prevents the browser's native context menu — no more "Save Image As…"/"Inspect" over what looks like a plain <canvas> — and opens a custom, Sheets-shaped menu instead: Cut, Copy, Paste, a separator, Insert row above, Insert row below, Insert column left, Insert column right, a separator, Delete row, Delete column, a separator, and Explain. Every row above Explain runs through the exact same command the top Edit/Insert menu already calls for the identical action — clipboard.cut/clipboard.copy/clipboard.paste and structure.insertRows/insertRowsBelow/insertColumns/insertColumnsRight/deleteRows/deleteColumns — so undo/redo, the command-history panel, and analytics all work identically whether the action came from the top menu or the right-click menu, by construction (one command path, not two).

The insert labels show the real row/column count for the current selection, matching Sheets' own grammar exactly: a single row/column keeps the singular, un-numbered "Insert row above"/"Insert column left" (Sheets never spells out "1"), while a 3-row selection shows "Insert 3 rows above"/"Insert 3 rows below" and a 2-column selection shows "Insert 2 columns left"/"Insert 2 columns right".

**Right-clicking a row-number/column-letter header directly — or a cell inside a header-originated whole-row/whole-column selection — opens a second, richer menu instead **, matching Sheets: only that ONE axis's items, not both. A row-header menu shows Insert row above, Insert row below, a separator, Delete row(s) N (or N-M for a multi-row selection, the real range), and Clear row(s) N — no column items at all; a column-header menu mirrors it with column items only. Clear is new here — it empties the selected row/column band's content (every cell in it) without deleting the rows/columns themselves or shifting anything, unlike Delete.

Try it

Right-click any cell to see the plain menu. Try Cut/Copy on one cell, then right-click another and Paste; try Insert row above/below or Delete row on a row inside the sample data; select a multi-row/column range first to see the label switch to the real count in both directions. Right-click a row NUMBER or column LETTER in the header strip to see the richer axis-only menu, including the new Clear item.

Verified behavior

Matches Google Sheets: In Google Sheets, right-clicking a single cell opens a menu whose first group is Cut/Copy/Paste/Paste special, followed by Insert (1 row above / 1 column left / cells…), then Delete (row / column / cells…) — live-verified; see this feature's oracle brief. For a MULTI-row/column selection, Sheets' own plain-cell menu spells out the real count and BOTH insert directions — "Insert 3 rows above" / "Insert 3 rows below", "Insert 2 columns left" / "Insert 2 columns right" — and a single row/column keeps the singular, un-numbered "Insert row above"/"Insert column left" (Sheets never spells out "1"). Studio's structure.insertRows/insertColumns commands already insert count rows/columns matching the selection's span for the "above"/"left" direction; structure. insertRowsBelow/insertColumnsRight add the missing "insert after the selection" pair, reusing the exact same Store.insertRows/insertColumns primitive with at one past the selection's last row/column instead of before its first. Sheets also right-click-selects the target the same way a left-click does — inside the current selection, the selection is left alone; outside it, the selection collapses to the clicked cell — which Studio's CanvasGrid.onContextMenu replicates.

The header-triggered menu (live-verified 2026-07-22; see this feature's oracle brief): right-clicking a row-number or column-letter HEADER in Sheets opens a DIFFERENT, richer menu than the plain-cell one — still Cut/Copy/Paste/Paste special first, but the Insert group offers BOTH directions ("Insert 1 row above" AND "Insert 1 row below" together for a header-selected row, live-confirmed), plus Clear row/Hide row/Resize row/Create a filter/Conditional formatting/Data validation/"View more row actions" (only Clear is in scope here — the rest have no backing Studio capability yet, per the issue's own non-goals list). For a MULTI-row/column header selection, this session's live drive of the exact real-range Delete/Clear label wording hit a shared-browser tooling collision (see the oracle's addendum) — Studio's own chosen wording, Delete rows {r0}-{r1}/Clear rows {r0}-{r1} (no spaces around the hyphen), is a disclosed divergence from any unverified exact Sheets spacing, not a byte-for-byte replication attempt. Studio's clear.selection command needed no new capability: a header-originated whole-row/ whole-column selection is structurally just a SelRange, identical in shape to any other selection clearEdits already handles.
