Some palettes, dialog boxes, and options bars contain settings that use pop‑up sliders (for example, the Opacity option in the Layers palette). If there is a triangle next to the text box, you can activate the pop‑up slider by clicking the triangle. Position the pointer over the triangle next to the setting, hold down the mouse button, and drag the slider or angle radius to the desired value. Click outside the slider box or press Enter to close the slider box. To cancel changes, press the Esc key.

To increase or decrease values in 10% increments when the pop‑up slider box is open, hold down Shift and press the Up Arrow or Down Arrow key.

Using different kinds of pop‑up sliders

A.

Click to open pop‑up slider box.

B.

Drag slider or angle radius.

You can also “scrub” some pop‑up sliders. For example, if you hold the pointer over the word “Fill” or “Opacity” in the Layers palette, the pointer changes to the Hand icon. Then you can move the pointer left or right to change the fill or opacity percentage.
