Keyboard shortcuts

Every key Signal Lab answers to, grouped by where it works. Shortcuts with a single letter or Delete never act while you type in a field.

TIP

In a browser on a Mac, ⌘ works wherever Ctrl is written below, except Ctrl+Space in a template field.

Anywhere

Keys	What they do
Ctrl+K	Opens Send a signal, the signal palette, on any screen — even while typing in a field. Again closes it
F1	Opens this documentation at the page of the screen you are on, like Documentation
Tab, Shift+Tab	Moves between controls. A control's tip shows as it takes the focus; any other key hides it
Space, Enter	Presses the button that has the focus — every clickable thing is a button
Esc	Closes the dialog that is open

In the signal palette:

Keys	What they do
Typing	Filters the signals
↑ ↓	Chooses a signal
Enter	Sends it and closes the palette
Esc	Closes the palette; so does a click beside it

Experiment editor

On the canvas — when no text field has the focus:

Keys	What they do
A	Opens the menu to add a node (Add node). With a node selected, the new one goes after it
Delete or Backspace	Removes the selected connection, or the selected nodes — never Start or End
Tab	Moves through the nodes, their ports and the connections; a node or a connection that takes the focus is selected
Enter or Space on an output, then on a node or its input	Connects them
← → ↑ ↓	Moves the selected nodes by 5 points (20 with Shift), while a node has the focus. One press-and-hold is one step of the history
Esc	Closes the add menu; else cancels a connection being drawn; else drops the selected connection; else clears a selection of several nodes; else leaves Fullscreen; else leaves Focus editor
Ctrl+Z	Undo
Ctrl+Shift+Z, Ctrl+Y	Redo
Ctrl+D	Duplicate: a copy of the selected nodes, with the connections between them
Ctrl+F	Finds a node by its type, what it does or its id
Ctrl+0	Fit graph: the whole graph in view
Ctrl+1	Reset zoom: 100 %
Ctrl+Enter	Send now — for a wait, Listen now: only the selected node, without running the experiment
Ctrl+A	Selects every node
Ctrl+C	Copy: the selected nodes and the connections between them; Start and End stay out, as with duplicating
Ctrl+X	Cuts them
Ctrl+V	Pastes nodes copied here or in another experiment, with new ids

Ctrl+A, C, X and V work on nodes while the editor has the focus, or while nothing has it and no text is selected on the page. With text selected elsewhere — in the Console, in a report — they are the page's own: Ctrl+C copies that text.

With the mouse:

Gesture	What it does
Drag on the empty canvas	Moves the view
Shift + drag on the empty canvas	Adds the nodes a frame touches to the selection
Shift or Ctrl + click on a node	Adds it to the selection, or takes it out
Drag one of several selected nodes	Moves them all
Double-click on the empty canvas	Opens the add menu there
Ctrl + wheel	Zooms at the pointer

In the add menu, the node finder and the properties:

Where	Keys	What they do
Add menu	Typing	Filters the nodes and saved signals
Add menu	↑ ↓, Enter, Esc	Choose, add, close
Node finder	↑ ↓	Choose a node
Node finder	Enter	Shows it on the canvas and selects it
Node finder	Tab	Back to the search field
Node finder	Esc	Closes it
Properties	Ctrl+Enter	Send now for the node shown
Properties	Esc in a field	Back to the canvas with the node selected, where A adds the next one

In a field that takes templates ({{name}}):

Keys	What they do
Ctrl+Space	Types {{ at the cursor and lists what can go there: parameters, variables, secrets, generators
Typing {{	Lists the same
↑ ↓	Chooses in the list
Enter or Tab	Inserts the choice and closes the }}
Esc	Closes the list; the field keeps the focus

In the experiment's dialogs:

Where	Keys	What they do
Parameters	Enter in the last parameter's value	Adds another parameter
Parameters, Run with…	Esc	Closes the dialog
Run with…	Enter in a field	Run experiment with these values
Secrets	Enter in a value	Saves it
Secrets	Esc in a value or a new name	Cancels; Parameters stays open

Signal library

Where	Keys	What they do
Signals	Ctrl+Enter	Send: sends the selected signal
Signals	Double-click on a signal	Sends it
A folder	F2	Rename folder
Renaming a folder	Enter, Esc	Keeps the new name, or cancels
A folder	Delete, twice	Remove folder; what is in it moves up a level
A folder	→ ←	Opens it, closes it
HTTP, OSC, MQTT senders	Ctrl+S	Save when the message is tied to a library signal (opened from it or saved there) and was changed; Save… when it is not in the library yet
Save to the library	Enter, Esc	Saves, or cancels

Tool screens

Screen	Keys	What they do
HTTP	Enter in the URL, a header, the credentials or the timeout	Sends the request
HTTP	Ctrl+Enter anywhere in the request, the body included	Sends the request
OSC	Enter in the target, the address or an argument	Sends the message
WebSocket	Enter in the URL	Connects
WebSocket	Ctrl+Enter in Message	Sends it
MQTT	Enter in Add a filter	Subscribes
Broadcast	Enter in Address or CIDR block — every mode but List	Send once

In Write to the developers: Ctrl+Enter in Message sends it (so does Enter in Your e-mail for an answer), Ctrl+V anywhere in the dialog pastes a screenshot from the clipboard, and Esc closes it.

Panes

The handles between panes — Console height, Properties width, Timeline height — take the focus with Tab:

Keys	What they do
↑ ↓	The console and the timeline: taller, shorter, by 16 pixels
← →	The properties: wider, narrower, by 16 pixels (the other way round when the interface reads right to left)
Shift + an arrow	Four times as far
Home, End	The smallest size, the largest
Enter	The default size; so does a double-click on the handle

Language menu

The flag and letters in the header.

Where	Keys	What they do
On the button	↓ or ↑	Opens the list
In the list	↓ ↑	The next language, the previous one
In the list	Home, End	The first, the last
In the list	A letter	The next language whose name — in its own language, yours or English — or letters start with it
In the list	Enter or Space	Switches to it
In the list	Esc or Tab	Closes the list
