Map Keyboard Shortcut Collisions Across Explicit Action Scopes

A shortcut alias can hide the same chord in two action descriptions. Normalize the modifier model and state which focus scopes can overlap before asking why one keypress sometimes triggers two actions.

1 · Action code | modifier+key chord | global or named focus scope

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.

Data note: The shortcut-scope matrix processes Action code | modifier+key chord | global or named focus scope locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

Perspective: Before: shortcut aliases and widget names hid overlapping key actions. After: a declared modifier model and explicit scope graph expose each colliding pair.

Shortcut-description reconciliation only, not a WCAG conformance or reserved-key certificate. Test real focus and event handling, off/remap options and assistive-technology interactions with a qualified accessibility specialist before deploying shortcuts.

HYPOTHESIS / PROTOTYPE: $4 is a proposed one-time price for filing the shortcut-scope matrix, not a current sales offer. No measured time saving or buyer demand is claimed. The optional manual-retyping baseline above estimates one export’s retyping budget only; it does not change the calculation or guarantee savings.

Filing prototype — checkout unavailable

Checkout is unavailable. Browser-local, profile-scoped convenience gating is best-effort, not server-verified access. A URL or browser flag is not proof of payment. Clearing browser data removes local state; no account or cross-device recovery is provided.

Optional filing controls are a local prototype.

Before using the shortcut-scope matrix

Primary is a source alias mapped only by the entered model: zero means Ctrl and one means Meta. Ctrl/Control and Meta/Cmd/Command are equivalent spellings; Alt and Shift remain separate modifiers. Chord modifier order is normalized, but duplicate modifiers after alias mapping are rejected as ambiguous source descriptions. The supported base keys are letters, digits, F1–F24 and the named keys listed in the guide. Scope names are case-insensitive codes; global overlaps every scope, while two different named scopes are assumed mutually exclusive. Actual browser event capture, bubbling, focus, nested widgets, remapping and reserved system or assistive-technology commands are not analyzed. Bare character keys receive a review note independent of collision count.

Boundary and sources

Method: Normalize aliases and modifier order, then compare each action pair once. A collision requires the same normalized chord and either a global scope or matching named scopes. Each row lists its peer actions, while the summary counts unique pairs. Bare letters, digits and printable named character keys are marked for separate single-character-shortcut review even when no listed action collides.

Google’s official pricing documentation, fetched 2026-10-01, says AI Studio is free in available regions. Optional formatting may require a Google account; manual local entry requires none. Limits can change and free-tier content may be used to improve products. Do not send private records.

Optional AI formatting, never the calculation

Manual entry completes this shortcut-scope matrix for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.

Format only these fictional or non-sensitive notes for a shortcut-scope matrix. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string"]}], "setting": "string"}. The columns are Action code | modifier+key chord | global or named focus scope; the setting is Primary modifier model: 0 Ctrl, 1 Meta. Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.

An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
