Diagram faster using mouse + keyboard shortcuts
There are many combination mouse plus keyboard shortcuts in diagrams.net that will speed up your drawing. You can select and deselect multiple shapes, resize grouped shapes in various ways, and swap, connect and clone shapes quickly.
You are probably familiar with the copy & paste keyboard shortcuts (
Ctrl+V) as they are used in almost all applications.
Combination or modifier keyboard shortcuts are when you press keys on your keyboard and it modifies a mouse action that you do at the same time.
All of the current modifier keyboard shortcuts in diagrams.net and draw.io are described below.
Note: macOS users should use
Cmd instead of
Option instead of
Alt in the shortcuts below.
Mouse + keyboard diagram shortcuts
Several modifier keyboard shortcuts work directly with or on the drawing canvas.
Open a diagram file: Hold
Shift while you
drag a diagram file onto the drawing canvas. Your diagram file will be opened in a new tab if you are using diagrams.net in your browser, instead of being pasted into your current diagram.
If you are using the diagrams.net Desktop app, and had previously made changes to an open diagram, you will be prompted to Save or Discard Changes before the editor opens the file you dropped on the canvas.
Open the context menu: Hold
left-click on the drawing canvas.
Zoom in and out: Hold
Ctrl+Shift and scroll the mouse
wheel to zoom the drawing canvas in and out.
Scroll horizontally: Hold
Shift and scroll the mouse
wheel to move the drawing canvas horizontally.
Pan drawing canvas: Hold
drag the drawing canvas around.
Deselect/reselect shapes: Hold
click on a shapes, or drag a selection box around the shapes you want to deselect or reselect.
Force a selection box: Hold
Alt and start
dragging to force a selection box, no matter what is selected or what what shapes are under your mouse. This will ignore all handles on shapes and connectors under the mouse (rotate, resize, and connection points).
Select intersecting shapes: Hold
Alt as you finish
dragging a selection box to select all the shapes and connectors that are fully and partially inside the selection box. This includes individual shapes that are part of a group.
Select the shape or connector underneath: When you have shapes or connectors stacked on top of each other, hold
click on the shape to select the next shape down the z-order stack, behind the currently selected shape.

You can use mouse + keyboard shortcuts to work with shapes that are already on the drawing canvas.
Clone a shape: Hold
drag a shape that is already on the drawing canvas to clone it.
Swap two shapes: Hold
drag one shape on the drawing canvas and drop it on another shape to swap the two shapes.
Move or resize shape and ignore grid: Hold
Alt as you move or resize a shape or group of shapes on the drawing canvas to move it smoothly and not ‘snap’ it to an exact alignment based on the editor grid.
Overlay shapes on containers: Hold
drag and drop a shape over a container shape to overlap the two shapes instead of adding them to the container shape.
Insert space and move shapes: Hold
drag the mouse from a blank section on the drawing canvas to insert horizontal and vertical space and move the nearby existing shapes.
Maintain proportions on resize: Hold
drag the grab handles on a shape to resize it while keeping the height and width relative to the shape’s original proportions.
Resize only the group’s outer boundary: Hold
resize a group with your mouse. The outer boundary of the group will be resized, but the shapes inside the group will not. This is called a non-recursive group resize.
Centered group resize: Hold
resize a group with your mouse to resize both the group and all of its shapes around its central point.
Ignore shape: Hold
drag and drop the end of a connector to overlap it on a shape without connecting to the shape.
Connect to a fixed point: Hold
Shift as you
drag the end of a connector and hover over a shape to display only the fixed connection points. Drop the connector on a connection point or at any point inside the boundary of the shape to connect it to that fixed point.
Using the shape libraries
Some mouse + keyboard shortcuts let you work quickly with shapes from the shape libraries.
Ignore current default style: Hold
click on or
drag a shape from the shape libraries. The new shape will have a white fill and a black outline, as per the original diagrams.net default style for shapes and not a custom default style that you have set.
Disable connections on drop: Hold
drag a shape from the library to disable the direction or connection arrows on the existing shapes on the drawing canvas. When you drop the shape, the editor will not try to auto-connect it.
Replace shape: Select a shape on the drawing canvas, hold
click on a shape in the shape library to replace the selected shape. This is faster than dragging a new shape from the shape library over an existing shape to replace it.
Insert a new shape at the bottom left: Hold
click on a shape in the shape library to add it to the drawing canvas at the bottom left of your diagram, underneath all other shapes. Normally, when you click on something in the shape libraries, it will be added to the center of your diagram, overlapping any existing shapes at that position.
Insert and connect a shape: Select the shape on the drawing canvas that you want to connect a new shape to, then hold
Alt+Ctrl and click on a shape in the shape library.
