Keyboard and Mouse Actions for Simulink Modeling

Note

On Macintosh platforms, use the command key instead of Ctrl.

Action Menu Search

You can access actions in the Simulink^® Editor using the Ctrl+. shortcut. For AZERTY keyboards, the equivalent shortcut is the Ctrl+Shift+. shortcut.

After the action menu appears, start typing the action name or description and select the action from the menu.

To enable context-sensitive search, you can select a part of the model before using the Ctrl+. shortcut. For example, you can select a Gain block.

While the shortcut menu is open, you can toggle between the block and action menus using the Ctrl+. shortcut.

Object Selection and Clipboard Operations

Objects include blocks, signal lines, signal labels, and annotations.

Task	Action
Select an object	Click.
Select additional objects	Shift+click.
Select all objects	Ctrl+A
Copy object	Drag with the right mouse button. Ctrl+drag.
Move any object, including signal labels	Drag.
Delete selected object	Delete or Backspace
Cut	Ctrl+X
Paste	Ctrl+V
Duplicate object	Ctrl+C, Ctrl+V
Undo	Ctrl+Z
Redo	Ctrl+Y

Block and Signal Line Shortcuts and Actions

Task	Action
Set the main parameter for selected block	Alt+Enter
Add a block at the current location from shortcut menu	Double-click and start typing the block name, then select the block from the menu.
Get prompted for suggested block based on context	Double-click at the end of a line drawn from an existing block, then select a suggestion from the list or start typing to select one from the library.
Open or hide the Property Inspector	Ctrl+Shift+I
Copy block or model from another Simulink Editor window	Drag between windows.
Move block	Arrow keys
Resize block, keeping same ratio of width and height	Shift+drag handle.
Resize block from the center	Ctrl+drag handle.
Rotate block clockwise	Ctrl+R
Rotate block counterclockwise	Ctrl+Shift+R
Flip block	Ctrl+I
Connect blocks	Click a port, then click the port you want it to connect to. Select the first block, then Ctrl+click a second block. Drag from port to port. Click a port and hold Shift as you connect to the next port. Hold Shift to make multiple, consecutive connections.
Draw branch line	Click a port, move the cursor near the line you want to branch, and then click after you see the preview. Select a line, move the cursor toward the element you want to connect with, and then click the port. Ctrl+drag line. Right-mouse button+drag.
Route lines around blocks	Shift+drag while drawing.
Interactively add ports to blocks that take multiple inputs	Drag toward the port from a compatible block or signal line. Drag from the edge of the block that you want to add the port to. Click the edge of the port, and then drag. Click the edge of the port, move the cursor over the signal type — signal, bus, or connector — from the menu, and drag.
Open block label text box for editing	Click the block label. Select the block and use F2. On Macintosh platforms, select the block and use control+return.
Disconnect block	Shift+drag block.
Create subsystem from selected blocks	Ctrl+G
Create subsystem or area from empty selection	To create the highlighted option, which you can change by using the arrow keys or mouse: Click inside the selection box. Press Enter. Press the number key associated with an option.
Open selected block	Enter
Go to parent of active subsystem or referenced model	Esc
Find block	Ctrl+F
Mask block	Ctrl+M
Look under block mask	Ctrl+U
Comment through a block	Ctrl+Shift+Y
Comment out or uncomment a block	Ctrl+Shift+X
Refresh Model blocks	Ctrl+K
For a linked block, go to the library of the parent block	Ctrl+L
Open Model Explorer	Ctrl+H

Signal Name and Label Actions

The signal name appears in a label on the signal line.

Task	Action
Name a signal line	Double-click the signal and type its name.
Name a branch of a named signal line	Double-click the branch.
Name every branch of a signal	Right-click the signal, select Properties, and use the dialog box.
Delete signal label and name	Delete characters in the label or delete the name in Signal Properties dialog box.
Delete signal label only	Right-click the label and select Delete Label.
Open signal label text box for editing	Double-click the signal line. Click the label. Select the signal line (not the label) and use F2. On Macintosh platforms, select the signal line (not the label) and use control+return.
Move signal label	Drag the label to a new location on the same signal line.
Copy signal label	Ctrl+drag the signal label.
Change the label font	Select the signal line (not the label), and then on the Format tab, click Fonts for Model.
