Alt+numbers	See comment.	For the Windows version only: run the corresponding Quick Access Toolbar command if a number is pressed above the character keyboard; otherwise, insert the corresponding ASCII character (requires use of the numeric keypad on Windows). To enter special ASCII characters on macOS, you can change to a specific Unicode Hex Input keyboard layout.

Ctrl+C	Command+C	Copy text in fields. Copy images in graphics and plot windows. Copy nodes in the Model Builder and Application Builder trees.
Ctrl+D	Command+D	Clear the selection of all domains, boundaries, edges, or points in the Model Builder. Clear all selections in form editor windows.
Ctrl+Shift+D	Command+Shift+D	Duplicate the selected node in the Model Builder and Application Builder.
