They use an offscreen native HTML5 input type=range element so that they can support the full range of keyboard shortcuts left, right, up, down, are all supported, as well as special combinations like function-left to move the range immediately to the left or right. There are a surprising number of subtle affordances in native inputs like range sliders, and to create a good drop-in replacement, it’s important to replicate as many as possible.`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":184,"value":"viewof ms = mood({ scale: 2, min: 100, max: 200, value: 150, step: 10 })","pinned":true,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":226,"value":"md`Slider value: ${ms}`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":349,"value":"md`---\n\n## Usage\n\nYou can use these sliders for your own notebooks!\n\n\\`\\`\\`js\nimport {mood} from \"@tmcw/mood\";\n\\`\\`\\`\n\nThe slider API is:\n\n- min, max, value, step: same meanings as they have with [the native HTML5 input type=range element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/range)\n- scale: pixel scale, to customize how big the slider looks.
