Connect blocks	Click a port, click the port you want connect to Select first block, Ctrl+click 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; 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 subsystems, buses, and other blocks that take multiple inputs	Drag toward the port from a compatible block or signal line Drag from the edge of the block or bus 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
Disconnect block	Shift+drag block
Create subsystem from selected blocks	Ctrl+G
Open selected subsystem	Enter
Go to parent of selected subsystem	Esc
Find block	Ctrl+F
Mask subsystem	Ctrl+M
Look under block mask	Ctrl+U

Comment out/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 signal and type 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 label or delete name in Signal Properties dialog box.
Delete signal label only	Right-click label and select Delete Label.
Open signal label text box for edit	Double-click signal line Click label
Move signal label	Drag label to a new location on same signal line
Copy signal label	Ctrl+drag signal label
Change the label font	Select the signal line (not the label) and use Diagram > Format > Font Style
