Keyboard Shortcuts
This page lists the keyboard shortcuts available in CyberViewer. Shortcuts that require an image only work after an image has been loaded.
The global shortcut works even when another application has focus:
| Shortcut | Action | Default |
|---|---|---|
Alt+Shift+V |
Show or hide the CyberViewer window. | Enabled |
To change it, open Settings > System, click Toggle hotkey, and press the desired combination. The new value is saved automatically. Use Backspace or Delete while capturing to clear the binding, or Escape to cancel capture.

The navigation zoom preference in Settings controls whether changing images resets the selected view or keeps the current zoom.
These are not keyboard shortcuts, but they are part of the main navigation controls:
| Gesture | Action |
|---|---|
| Mouse wheel | Zoom around the pointer position. |
| Drag with the primary mouse button | Pan a zoomed image. |
| Two-finger pinch | Zoom on a touch device. |
| Double-click | Run the configured double-click action. |
| Shortcut | Action |
|---|---|
Q |
Rotate 90 degrees counter-clockwise as a pending preview. |
E |
Rotate 90 degrees clockwise as a pending preview. |
C |
Open the crop tool. |
R |
Open the resize tool. |
J |
Open the color adjustment tool. |
H |
Flip horizontally and create a copy. |
Shift+H |
Flip vertically and create a copy. |
When a rotation preview is pending, Enter saves it and Escape discards it. While crop, resize, or adjustment mode is active, Enter confirms the operation when the focused control allows it, and Escape cancels it.

Copy the current image to the clipboard as PNG data. |
Ctrl+V |

See Slideshow for intervals, loop behavior, and presentation controls.
Escape closes or cancels the highest-priority active surface:
- Close the shortcut guide or main menu.
- Cancel crop mode.
- Discard a pending rotation.
- Stop an active slideshow.
- Leave fullscreen or close an open modal.
The global shortcut field is in Settings > System. Click it to capture a new key combination. CyberViewer saves the value as soon as capture finishes. If Windows or another application already owns the accelerator, the registration may fail and the shortcut will not toggle the window until a usable combination is selected.
