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.

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

Menu bar (macOS only)

NegPy has a menu bar on macOS, with 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.
