Keyboard shortcuts

Graphium keeps its shortcut list short on purpose: a handful of keys for capturing, saving, and labeling, so your hands stay on the keyboard while you write. This page lists every shortcut, when each one is active, and where the app itself reminds you of them.

A note on notation: ⌘ is the mac Command key, ⇧ is Shift, and ⌥ is Option. On Windows and Linux, ⌘ becomes Ctrl and ⌥ becomes Alt — every shortcut below is listed in both forms.

General

mac	Windows / Linux	What it does
⌘K	Ctrl+K	Opens the Composer — a single box to find a note or ask AI. Works from any screen; where no note is being edited — or no AI model is set up in Settings — it opens in search-only form. See AI chat and Ask.
⌘⇧M	Ctrl+Shift+M	Opens the quick memo dialog from anywhere in the app — note editor, note list, any screen. Memos are the raw material you capture now and use later.
⌘D	Ctrl+D	Duplicates the block the cursor is in, directly below it. Works inside the editor only — see Duplicating a block.
⌘F	Ctrl+F	Opens Find in note — search within the current note with highlighted matches. When no note is open, the browser's own find works as usual.
⌘\	Ctrl+\	Collapses or expands the sidebar for distraction-free writing. Desktop-size screens only — small screens have no permanent sidebar to collapse. On JIS keyboards, the ¥ key works too.
Esc	Esc	Closes the Composer, the in-note search bar, the quick memo dialog, and most other dialogs.

Saving

mac	Windows / Linux	What it does
⌘S	Ctrl+S	Saves the current note immediately. Graphium also autosaves, so this is for peace of mind before you step away. Works in the main editor and in the side peek.
⌘⇧S	Ctrl+Shift+S	Saves a version — a named snapshot you can revisit, compare, and fork from the History panel.
⌘⌥S	Ctrl+Alt+S	Same as above. A fallback for when your OS, browser, or an extension reserves ⌘⇧S and the keystroke never reaches Graphium.

Versions are for your own notes: knowledge pages generated by AI don't take snapshots. If neither snapshot shortcut works in your environment, the Save version item in the note's ⋯ menu does the same thing.

Labels

These four shortcuts apply an inline label to the text you have selected. They work inside the body of a step block — the part of your note that becomes a step in the provenance graph. Pressing the same shortcut on already-labeled text removes the label.

mac	Windows / Linux	Label
⌘⇧I	Ctrl+Shift+I	Input — a material or ingredient the step uses
⌘⇧E	Ctrl+Shift+E	Tool — the instrument or software used (E as in Equipment — ⌘⇧T is reserved by browsers for reopening closed tabs)
⌘⇧P	Ctrl+Shift+P	Parameter — a setting or condition
⌘⇧O	Ctrl+Shift+O	Output — what the step produces

A few boundaries, all deliberate:

• Labels can only be added inside a step's body — not in the step title (that names the activity itself) and not inside table cells (tables are interpreted structurally instead). Removing an existing label works anywhere.
• The same four buttons appear in the floating toolbar whenever you select text, so the shortcuts are optional.

Confirming

mac	Windows / Linux	What it does
⌘Enter	Ctrl+Enter	Sends or confirms in multi-line inputs where plain Enter inserts a line break: the AI chat, the Composer, the citation pickers, the quick memo dialog, and forms in Settings (for example, adding an MCP server).

Typing triggers

Two characters act as menus while you write. They aren't modifier shortcuts, but they belong in the same muscle memory:

Type	Where	What it does
/	On an empty line	Opens the slash menu — blocks (steps, tables, formulas, callouts…), media, citations, and templates. See Notes & editor.
@	Anywhere inline	Opens a search menu to link another note, a material, or a knowledge page — or create a new note on the spot.

An empty note shows a small guide card with exactly these three entry points — Ask AI (⌘K), Link a note (@), and Slash menu (/) — so your first note teaches you the essentials.

Good to know

Label shortcuts follow key positions, not characters. ⌘⇧I and friends are detected by the physical key position, so they work identically on US, JIS, and other keyboard layouts — no matter what character the key prints.

There is deliberately no shortcut for a new note. ⌘⇧N is reserved by browsers for a new private window and can't be reliably overridden, so a shortcut there would misfire for some users. Use the + Note button in the sidebar instead. Memos get a shortcut and notes don't, and that asymmetry is intentional: memos are for instant capture, notes are where you sit down and write.

The app reminds you as you go. You don't need to memorize this page — the shortcuts appear right where you'd use them:

• The floating toolbar's label buttons show keycap hints (⌘ ⇧ I) and tooltips.
• The sidebar's + Memo button tooltip reads Capture a quick memo (⌘+⇧+M), and the sidebar toggle reads Collapse sidebar (⌘+\).
• The note's ⋯ menu shows the snapshot shortcut next to Save version.
• The Composer's footer shows ⌘Enter to send and Esc to close, and the quick memo dialog says Press ⌘+Enter to save.

Using the desktop app?

In the desktop app, the quick memo shortcut also lives in the native menu bar, so it works even in the rare cases where the system swallows the keystroke before the page sees it.
