Shortcuts & Hidden Features

Here is a collection of features that are not obvious, but everyone should know.

Tab key (Tab): Hides/shows all sidebars at once. Perfect for briefly assessing the image in large size.
Ctrl + Shift + L: Toggles “ISO 12646 Mode” (white border around the image in Darkroom mode to assess colors more neutrally).
B:Hides the borders/arrows for expanding the panels.
Shift + t: Tooltips on/off.

This is the biggest “Aha moment” for many:

Right-click on a slider: Opens a graphical pop-up where you can adjust the value much more finely or type it in directly.
Double-click on a slider: Resets it to the default value.
Mouse wheel over slider: Changes the value.
- Trick: If you hold Ctrl while doing this, you change the value in much smaller steps (fine-tuning).

Mouse wheel inside mask circle: Changes the size
Shift + Mouse wheel: Changes the soft edge (hardness) of the mask.
Ctrl + Click on a shape: Adds a new point to a path (or closes it).
Right-click on a shape: Deletes the point or the entire shape (depending on context).
Show masks (Yellow): Click on the small yellow circle icon at the bottom right of the module (next to the mask symbol) to see the mask permanently displayed in yellow.

z: Preview mode (Zoom). Shows the image under the mouse immediately in large size as long as you press the key. (Or Alt + w for permanent full screen).
Ctrl + F: Focus peaking in the lighttable! Shows you with colored edges which parts of the image are sharp. Brilliant for culling.
Keys 1–5 assign stars. Key 0 removes stars. Key r (reject) rejects.
Ctrl + c / Ctrl + v: Copies the complete history stack from one image and pastes it onto another.
- Pro Tip: Ctrl + Shift + c opens a dialog where you can select which modules you want to copy (e.g., only the white balance, but not the exposure).

Right-click + Drag (on image): Rotates the image / straighten horizon. Only works if the “Rotate and Perspective” module is active (it usually is).
Select any edit in “history” (History Stack), click on “take snapshot” in Snapshot module: Creates a snapshot at this point. You can then click on the at the top to get a split-screen (Before/After) comparing it to other edits.
Mouse wheel over the image: Zooms in/out.
- Important: The center of the zoom is where the mouse is.

Mouse wheel / Touchpad to scroll menus: Mouse wheel scrolls through the modules of the side panels by default – Activate.

Now the sliders can be moved with Shift / Ctrl / Alt.
