Select Block Diagram Elements

Selected elements have a solid blue outline. The most recently selected element has blue corner brackets in addition to the outline. To represent the cursor when you use the keyboard for selection, a blue box with dashed lines surrounds the element.

Task	Action
After clicking or moving elements, access keyboard shortcuts for selecting elements	M to toggle between modifying selection and moving selected elements.
Change selection to closest similar element in a direction	Left, right, up, or down arrow
Move cursor to closest element in a direction, regardless of similarity	Ctrl+Shift + left, right, up, or down arrow

Select additional adjacent elements	Drag from empty position. Shift + left, right, up, or down arrow
Select additional elements that are not adjacent	Shift + click. Ctrl + left, right, up, or down arrow to change the current element. Ctrl + space bar to add the current element to the selection. On a Mac, to add the current element to the selection, press command+shift + space bar or shift + space bar.
Select all blocks, lines, and annotations	Ctrl+A

Modify Block Diagram Elements

Task	Shortcut
Set main parameter for selected block	Alt+Enter
Open or hide the Property Inspector	Ctrl+Shift+I
Connect blocks	Click a port. Click the blue chevron symbol that appears near a compatible port you want 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.
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 blue chevron symbol that appears near the port. Ctrl + drag line. Right mouse button + drag.
