Keyboard shortcuts and gestures

A grouped reference of every keyboard shortcut and mouse gesture in Tone Caliper — personas and tabs, comparing, color selection, crop, and the Library.

This page lists every keyboard shortcut and mouse gesture, grouped by task.

On a Mac, use ⌘ wherever the shortcuts below show Ctrl.

Personas and tabs

Hold Ctrl with a number to jump between personas; inside the Editor, the bare number keys switch tabs instead.

Key	Action
`Ctrl`+`1`	Go to the Library
`Ctrl`+`2`	Go to the Editor
`Ctrl`+`3`	Go to Export
`1`	Tone tab
`2`	Color tab
`3`	B&W tab
`M`	Toggle Color / B&W
`F`	Fit the wheel to your photo's colors
`0`	Show the full wheel

Comparing and inspecting

Hold B to see the original, or hold H to highlight what the selected pin catches.

Key	Action
Hold `B`	Show the ungraded original
Hold `H`	Highlight what the selected pin catches

Selection and color

Scrolling zooms the view, but scrolling over a selected pin tunes that pin instead.

Gesture / key	Action
Click a color	Drop a pin on it
Scroll over a pin	Grow or shrink its range
`Shift`+scroll over a pin	Soften the pin's edge
`Alt`+scroll over a pin	Spin the pin's hue
Double-click a pin	Delete it
Right-click a pin	Open its "Lightness range" menu
`Ctrl`+drag on the photo	Sample a region as your color
`Delete` / `Backspace`	Remove the selected pin
`Esc`	Step back, then deselect
`Ctrl`+`Z`	Undo
`Ctrl`+`Shift`+`Z` or `Ctrl`+`Y`	Redo

The mouse wheel zooms toward the cursor, and middle-drag or Space+drag pans the wheel and the photo together.

Crop and rotate

Many controls reset on a double-click, including the straighten angle.

Key	Action
`C`	Toggle crop
`[` or `]`	Rotate the frame

Library and the loupe

Space pans in the Editor, but in the Library it opens a full-resolution loupe for culling.

Key	Action
`Space`	Open or close the loupe
`F`	Favorite
`I`	Toggle info
`Enter`	Open in the Editor
`←` / `→`	Move the selection
`Ctrl`+`A`	Select all visible
`Esc`	Close the menu

Inside the loupe, \ toggles edited versus original, ← / → walk the set, and the Full res button renders the current view at native resolution.
