# Magic Bullet Looks

### Controls Pane

In traditional color grading, computer mice were rarely used. Instead, professionals employed dedicated panel peripherals loaded with knobs and trackballs. These provided a more tactile, intuitive means to manipulate the wheel-type controls for adjusting color channels, saturation, shadows, highlights, and many other factors. (To learn more about these controls, check out our Colorista user guide page on [3-Way Correction](https://help.maxon.net/rg/en-us/#html/magic-bullet-colorista/3-way-correction.html?TocPath=Magic%2520Bullet%2520Suite%257CMagic%2520Bullet%2520Colorista%2520V%257CInterface%257C_____2).)

In Looks, the Tilde key (~) toggles Trackpad Mode on and off, allowing you to use your trackball or integrated trackpad as you would a traditional panel’s trackball.

This pop-up explainer appears when you click the three-dots icon to the left of CONTROLS.

### Trackpad Mode

Trackpad Mode lets you edit the numeric values of a tool’s controls with the touch of a trackpad, trackball, or mouse. Every control can be customized in Trackpad Mode, and built-in keyboard mapping aids in moving between controls as you edit their values.

Let’s illustrate how to use Trackpad Mode with the Hue/Saturation tool.

**Step 1.** With the tool selected, press the Tilde (~) key, located next to the 1 key on US/Canadian keyboards. You’ll notice that enabling Trackpad Mode turns the three-circles icon from white to orange.

**Step 2.**Use the arrow keys to select the Component Balance wheel.

**Step 3.** Use the mouse or trackpad to push the center dot away from the greens toward the reds or blues.

**Step 4.** Use the scroll wheel to scroll up/down and change luminance. When finished, press Enter or Tilde to exit Trackpad Mode.

### Trackball Mode keyboard shortcuts

Looks uses the following keyboard controls in Trackball Mode:

- **Tilde (~):** Enter/exit Trackball Mode.
- **Esc or Enter:** Leave Trackball mode and accept changes.
- **Up/Left arrow:** Move to the control above the current one. If at the topmost control, selection wraps around to the bottom.
- **Down/Right arrow:** Move to the control below the current one. If already on the last list entry, selection wraps around to the top.
- **Cmd/Ctrl + Z:** Undo the last change (works without leaving Trackball Mode).
- **Cmd/Ctrl + Shift + Z:** Redo the last change (works without leaving Trackball mode).
