Get familiar with how to navigate the PureRef window.

The PureRef window

When you open PureRef you will see something like this:

There's nothing here!

Drop some images to get started.

It may just look like a grey box, but this is an empty PureRef scene! It's a window with a canvas inside, which will be visible once you drop some images in PureRef. Try it!

Right click menu

Right mouse button/Right mouse button

The other main part of the interface is the menu. To let you really focus on what's important, the only thing always on screen is your images. Everything else is done though shortcuts or the right click menu. This is your fast lane to all the features, actions and settings PureRef has to offer. Everything in it will be covered in this handbook.

Keyboard shortcuts

To stay true to being as minimal as possible, nearly everything in PureRef can be done through keyboard shortcuts. Most of them can also be re-bound to whatever fits your workflow the best. See the default keybindings here, your current keybindings in Settings, where you can also re-bind them.

Move window

Right mouse button/Right mouse button

Move the PureRef window by pressing the shortcut buttons while moving the cursor.


• Move window threshold - Adjust distance threshold between moving the PureRef window and opening the right click menu, in pixels.


Left mouse button Alt/Left mouse button Middle mouse button/Middle mouse button

Move around inside the canvas area by holding down the shortcut buttons while moving the cursor.


When using track pads, setting the scroll to pan is an excellent choice. Ctrl/ + Scroll zooms even if scroll wheel is set to pan instead of zoom.


• Scroll wheel functionality - Set scroll wheel interaction behaviour: Pan canvas, zoom canvas or nothing.


Left mouse button Z/Left mouse button Z

Zoom in and out by using the scroll wheel, or by holding Z while holding down the Left mouse button and moving the cursor.

Resize window

Left mouse button/Left mouse button

Grab the corner of the PureRef window to resize the PureRef window.


• Resize border width - Adjust size of the interactable edge/corner area for resizing the PureRef window, in pixels.

• Scale scene on window resize - Enable to allow the canvas zoom to keep up accordingly when resizing the PureRef window, instead of staying static and cropping the view area.

Resize to selection

Window > Resize to selection


Resizes the PureRef window to fit selected images. If nothing is selected, resizes the PureRef window to fit all images in the scene.


Window > Maximize


PureRef will go fullscreen. Toggle off or move the window to go back to windowed mode.


• Show maximized on top of taskbar - Set whether Maximize should cover the taskbar or not.

• Lock window while maximized - Enable to force the PureRef window to stay maximized when attempting to move it. Move will function like Pan (While Maximized).


Window > Minimize


Minimize window to taskbar/dock. Click the icon in the taskbar/dock to restore the PureRef window.

New scene

New scene

#clear #reset
