Keyboard Shortcuts

The following table summarizes the available keyboard shortcuts on Windows and Linux and on macOS (see also Keyboard Shortcuts for the Quick Access Toolbar and the Application Builder documentation for specific keyboard shortcuts):


Shortcut (Windows, Linux)	Shortcut (macOS	Action
F1	F1	Display help for the selected node or window.
Ctrl+F1	Command+F1	Open the COMSOL Documentation front page in an external Help window.
F2	F2	Rename the selected node, file, or folder.
F3	F3	Disable selected nodes.
F4	F4	Enable selected nodes.
F5	F5	Update solution with respect to new definitions without re-solving the model. Update reduced model data. Also, on Windows, to continue in the Method Editor’s debugging tool in the Application Builder.
F6	F6	Build the preceding node in the Geometry branch or plot the previous plot for a time-dependent, eigenfrequency, or eigenvalue solution. Also, on Windows, to step in the Method Editor’s debugging tool in the Application Builder,
F7	F7	Build the selected node in the geometry and mesh branches, compute the selected study step, compute to the selected node in the solver sequence, or plot the next plot for a time-dependent, eigenfrequency, or eigenvalue solution. Also, on Windows, to step into in the Method Editor’s debugging tool in the Application Builder.
F8	F8	Build the geometry, build the mesh, compute entire solver sequence, update results data, update the plot, or run model method in a method call. Also, on Windows, to create an executable or an add-in in the Application Builder.
F9		On Windows, check syntax for a method in the Application Builder.
Del	Del	Delete selected nodes and selected geometry objects.
Left arrow (Windows); Shift + left arrow (Linux)	Left arrow	If you are at the top of a branch, pressing this collapses this branch in the Model Builder. Continue pressing the left arrow key to move upward in the tree to collapse all branches. If within a subbranch, pressing the left arrow key repositions you to the beginning of the branch.
Right arrow (Windows); Shift + right arrow (Linux)	Right arrow	Expand a branch in the Model Builder.
Up arrow	Up arrow	Move to the node above in the Model Builder. Highlight the next entity for a 3D geometry in the Graphics window when it has focus.
Down arrow	Down arrow	Move to the node below in the Model Builder. Highlight the previous entity for a 3D geometry in the Graphics window when it has focus.
Alt+left arrow	Ctrl+left arrow	Move to the previously selected node in the Model Builder.
Alt+right arrow	Ctrl+right arrow	Move to the next selected node in the Model Builder.
Ctrl+A	Command+A	Select all domains, boundaries, edges, or points; select all cells in a table or all contents of a table cell.
Ctrl+C	Command+C	Copy text in fields. Copy images in graphics and plot windows.
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.
Ctrl+F	Command+F	Find a search string in a model or application method.
Ctrl+G	Command+G	Group nodes.
Ctrl+Shift+G	Command+Shift+G	Ungroup nodes.
Ctrl+K		Create, use, or rename a shortcut to an Model Builder node (for use in the Application Builder).
Ctrl+L	Command+L	Take a quick image snapshot.
Ctrl+N	Command+N	Create a new model.
Ctrl+O	Command+O	Open a model file.
Ctrl+P	Command+P	Print the contents of the plot window.
Ctrl+S	Command+S	Save a model file.
Ctrl+V	Command+V	Paste copied text.
Ctrl+Y	Ctrl+Shift+Z	Redo the last undone operation.
Ctrl+Z	Command+Z	Undo the last operation.
Ctrl+1		Create a local variable or correct the type of an existing variable in methods.
Ctrl+7		Toggle comments on and off in methods.
Ctrl+up arrow	Command+up arrow	Move a definitions node, geometry node, physics interface or feature node (except default nodes), material node, mesh node, study step node, or results node up one step.
Ctrl+down arrow	Command+down arrow	Move a definitions node, geometry node, physics interface or feature node (except default nodes), material node, mesh node, study step node, or results node down one step.
Ctrl+Tab	Ctrl+Tab	Switch focus to the next window on the desktop.
Ctrl+Shift+Tab	Ctrl+Shift+Tab	Switch focus to the previous window on the desktop.
Ctrl+Shift+A		Switch to the Application Builder window from the Model Builder.
Ctrl+Shift+M		Switch to the Model Builder window from the Application Builder.
Ctrl+F4	Command+W	Close the active window in COMSOL Desktop, if it is closable.
Ctrl+F8		Test an application.
Ctrl+Alt+left arrow	Command+Alt+left arrow	Switch focus to the Model Builder window.
Ctrl+Alt+right arrow	Command+Alt+right arrow	Switch focus to the Settings window.
Ctrl+Alt+up arrow	Command+Alt+up arrow	Switch focus to the previous section in the Settings window.
Ctrl+Alt+down arrow	Command+Alt+down arrow	Switch focus to the next section in the Settings window.
Shift+F10 or (Windows only) Menu key	Ctrl+F10	Open the context menu.
Ctrl+Pause	Command+. (Command + period)	Stop running a method when test running applications.
Ctrl+Space, Ctrl+/	Ctrl+Space, Ctrl+/	Open list of predefined quantities for insertion in text fields and table cells for expressions. Ctrl+/ is an alternative primarily intended for users of Asian Windows versions.
+, -	+, -	Highlight the next or previous entity for a 3D geometry in the Graphics window. Expand or collapse a branch in the Model Builder.
R	R	Toggle between automatic and manual rotation center for mouse rotation in 3D.
X, Y, Z	X, Y, Z	Press to force rotation around the x, y, or z axis, respectively, when you move the mouse in 3D.
