NOTE: Exclusively available on Sketchbook Pro for MacBook Pro users
For MacBook Pro users, quick access icons and sliders are available in the Touch Bar for undoing/redoing and changing brush/color attributes.
Default
This is the default state of the Touch Bar when using Sketchbook Pro. It contains buttons for undoing and redoing an action, as well as for accessing the brush size, brush opacity, slant, or amount/density/strength, and color sliders.
The tool you are in will determine whether certain Touch Bar options are accessible. For example, when zooming in, rotating, or moving the canvas, only Undo and Redo are accessible. When using Fill, Undo, Redo, and the Color Sliders are accessible.
For the following tools, all buttons are accessible: Ruler, Ellipse, French Curve, Perspective Guides, Symmetry, Steady Stroke, Predictive Stroke, and Draw Styles.
Brushes
For the brush buttons, the first one will always control size. The second button will be determined by the current selected brush. For some brushes, this button will change brush opacity. For others, it could be slant or amount/density/strength.
Brush Size
When you tap the Brush Size option in the Touch Bar, this is what you see. Tap-drag to change the size of your brush. When finished, tap (the Quit icon).
Brush Opacity/Slant/Amount/Density/Strength
When you tap the second button option in the Touch Bar, you will see one of these. Tap-drag to change that parameter of your brush. When finished, tap (the Quit icon).
Color Sliders
There are three Color Sliders: Hue, Saturation, and Luminance. When you tap one of these options in the Touch Bar, you will see one of the following. Tap-drag to change the color. When finished, tap (the Quit icon).
