'd' and 'u' scrolling aren't working

[peppy]

If you're hitting the same issue that I was, this comes from having missing bindings from the config binding list. ie. I didn't have duplicateTab in there, which was causing a parsing error and skipping some of my other bindings, including scrollUpHalfPage / scrollDownHalfPage.

Here's my working config with the required binding list:

 {
  "excludedUrls": "https://monkeytype.com, https://docs.google.com",
  "linkHintCharacters": "asdfjklweio",
  "detectByCursorStyle": false,
  "scrollSize": 250,
  "openTabUrl": "https://google.com",
  "modifier": "",
  "smoothScroll": true,
  "scrollDuration": 25,
  "transparentBindings": true,
  "bindings": {
      "hintToggle": [ ";", "f" ],
      "newTabHintToggle": "shift+;",
      "scrollUp": [ "k","up"],
      "scrollDown": [ "j", "down" ],
      "scrollLeft": "h",
      "scrollRight": "l",
      "scrollUpHalfPage": ["ctrl+u", "shift-space"],
      "scrollDownHalfPage": ["ctrl+d", "space"],
      "goToPageTop": "g g",
      "goToPageBottom": "shift+g",
      "goToFirstInput": "g i",
      "goBack": "ctrl+o",
      "goForward": "ctrl+i",
      "reload": "r",
      "tabForward": "ctrl+l",
      "tabBack": "ctrl+h",
      "closeTab": "x",
      "openTab": "t",
      "duplicateTab": "y t"
  }
}

Feel free to cross-check and add any missing bindings and see if it fixes the issue for you.
