| ShiftKey + dragging | Fine adjustment, 1/5 sensitivity to mouse movement |
| Mouse Wheel | Upward : increase value Downward : descrease value |
| ShiftKey + Mouse Wheel | Fine adjustment, 1/5 sensitivity to mouse movement |
| Keyboard (after focused) | Up / Right arrow : increment value Down / Left arrow : decrement value |

## Attributes

|Attribute|Description|
|---------|-----------|
|data-diameter = "nnn"|Set the width and height of the knobs or switches in 'px'.This is equivarent to 'data-width="nnn" data-height="nnn"'. In default, 64 for knobs and 32 for switches.|
|data-width = "nnn" data-height = "nnn"|Set the width and height of the knobs, sliders or switches individually in 'px'. In default, 64 for knobs, 128 for sliders and 32 for switches. If the size for slider is vertically long, the slider will be a vertical slider.|
|data-src = "Image URL"|Use external image for the knobs/switches. For Knobs, the image should be single knob-image that pointing upward (12 O'clock), or a vertically stitched knob-images that represent rotation of the knob frame by frame. For Sliders, the image should be a vertically stitched slider-images that represent thumb sliding from min value to max value frame by frame. For Switches, this image should be a vertically stitched Off state and On state image. If no image is supplied, input-knobs uses knob/slider/switch images embedded inside (black body and red indicator)|
|data-sprites = "nnn"|For Knob / Sliders only. If you use frame stitched knob/slider-image, this attribute should be the number of frames - 1. The knobs that specified 'data-src' but not specified this attribute, it will use image rotation instead of frame switching procedure. The sliders that specified 'data-src' but not specified this attribute, the image is used as slider thumb part and the background is filled by 'data-bgcolor' .|
|data-fgcolor = "color"|Change Knob / Slider / Switch 's pointer color when no external image (data-src) is used. Default is red "#f00".|
|data-bgcolor = "color"|Change Knob / Slider / Switch 's background color when no external image (data-src) is used.Default is black "#000".|
