Quick Help under Ctrl+Shift+H — a complete on-page guide
The Ctrl+Shift+H shortcut used to be a small detail — it opened a short Output Console API help. In version 3.0 we rebuilt it into a complete guide to the on-page extension UI: global shortcuts, in-window shortcuts, Output Console, mouse interaction with windows, action-bar edit mode, logging. It works globally on every page where the extension is enabled, in a two-column layout, in 8 languages. This post walks through what you get under that one key.
What Quick Help shows now
The popup has six section cards, each with bullets:
- Global shortcuts —
Ctrl+Alt+G/H/J/K(TEMP windows),Ctrl+Alt+\(AI Helper),Ctrl+Alt+S(action-bar edit mode),Ctrl+Alt+I/O/P(edit panel in a separate window). - Inside a window —
Ctrl+Enter(run code),↑/↓(JS Console history),Ctrl+L(clear console),Esc(close the search bar). - Output Console —
Ctrl+Shift+L/K, six counted tabs,Alt+click/Alt+Shift+clickon Network (include / exclude domain), resizable DataLayer columns. - On-page windows — by mouse — drag, 8 resize handles, edge snap, header menu, double-click the bar = TEMP window size toggle, scroll containment (the wheel does not scroll the page underneath).
- Action-bar edit mode —
Ctrl+Z(undo),Delete,Esc, Shift/Ctrl+click selection, labels. - Logging into the Output Console — the
window.JUSTZIX.log/warn/error/info/debugchannel (plus theJZand__JUSTZIX__aliases) and interceptedconsole.*.
The popup footer links to the full manual (help-*.html inside the extension) — always within reach when you need deeper context.
Two-column layout (v3.0.1)
The first version was a single narrow (640 px) column you had to scroll. Now the popup is min(1040px, 94vw) wide — it uses the room the screen gives it. Content sits in two columns, each section is a separate card (background, border, a subtle shadow) — a clear layout instead of one wall of text. The footer with the link to the full manual lives outside the scroll area — always visible at the bottom. On screens narrower than 720 px the columns collapse to one, without losing readability.
Works globally — no Output Console required
The earlier Ctrl+Shift+H listeners only registered once the first Output Console rendered on the page. If a tab had no Output Console, the shortcut simply did nothing. From v3.0 the listener installs at content-script start and works globally on every tab where the extension is active. Whether or not you have any windows open — press Ctrl+Shift+H and the full cheat sheet appears.
How to open and close
The shortcut works the same on every operating system: Ctrl+Shift+H opens the popup, pressing it again closes it. You can also close it via:
Esc— the natural exit gesture;- a click outside the popup (anywhere on the page);
- the × in the popup's top-right corner.
The popup is draggable — grab the header bar and move it if it covers what you are reading. The position is remembered for the tab.
Eight languages — no external resources
The content is translated into 8 languages (PL, EN, DE, ES, FR, IT, RU, ZH) and lives in the lib/i18n.js dictionary under the helpPopup.* key. The popup language follows the extension's UI language — change it in the options and the popup updates with it. The popup itself is rendered by the content script with no external fonts or assets — it works even offline.
Why we made the change
Before, a new user hit Ctrl+Shift+H and saw a few lines about the window.JUSTZIX.log API. That was precise help, but narrow. Meanwhile, the vast majority of questions were about handling windows, TEMP shortcuts, action-bar editing and the Output Console — things you had to dig out of the full manual. The popup was supposed to be "the cheat sheet within reach" but had become a guide to one API surface. Version 3.0 returns to the original intent: a complete on-page cheat sheet under one key.
