Keyboard Shortcuts

Every shortcut, including the slider steps, can be changed in the app. Press ? for the shortcut overlay, then click Customize. Slider shortcuts are shown as merged rows (for example Density ↑/↓) with a Step column. The defaults are listed below.

A slider shortcut reports its new value in the canvas HUD, so you can keep a control on a hidden tab and still read what you set.

A control that the current mode or a lock has retired does not move by keyboard. Temperature on a B&W frame is an example: the shortcut changes nothing, and the HUD shows the control name instead of a value. A control on another tab, in a collapsed section or behind a closed panel still works.

Ctrl in this list is ⌘ on macOS. The app writes each key the way your platform writes it, so a menu, a tooltip and the overlay show ⇧⌘C there and Ctrl + Shift + C elsewhere.

Numpad keys can be bound separately from the number row (for example Num+9 and 9). Num Lock must be on for numpad digits.

Actions with no default key are not listed; every one of them can still be bound in Customize.

While a test strip or ring-around is up, [ and ] turn that proof's ladder instead of the image. While the paper test strip is up, ← and → step to the neighbor paper instead of the neighbor file, Enter keeps the paper shown full frame, and Esc goes back to the strip. The first Esc clears in-progress points; the second puts the tool down.

Mouse

Input	Action
Mouse Wheel	Zoom in / out (up to 400%); Reverse scroll zoom in Preferences flips the direction
Alt + Mouse Wheel	Brush Size up / down, for the heal, scratch and exclusion brushes
Pinch	Zoom in / out; sizes the brush instead while the Heal or Scratch tool is live, or a right-click is set to exclude
Middle Click + Drag	Pan zoomed image
Left Click + Drag	Pan zoomed image (when no tool is active)
Space + Left-Drag	Pan zoomed image while a canvas tool is active

Menu bar (macOS only)

NegPy has a menu bar on macOS: Preferences… sits in the application menu, and there is a Window and a Help menu. These keys come from it. They are platform window commands, not NegPy actions, so they are fixed and do not appear in the shortcut editor.

Key	Action
⌘ + M	Minimize the front window
⌘ + W	Close the front window (closing the main window quits NegPy)

Every other menu item uses the binding listed above for its action, and shows it only when that binding uses ⌘. A shortcut bound to a plain key still works from the keyboard; the menu just does not print it, because macOS gives a menu key priority over everything and a plain ? would fire while you type into a text box.
