解决atom使用ELAN触摸板时编辑器滚动异常问题

• atom 滚动异常是因为atom把触摸板的滚动事件识别为光标键按键事件了

• 通过配置编辑器快捷键可以实现通过同时按下alt-cmd时使用触摸板正常滚动编辑器的功能

keymap.cson

'atom-workspace':
  'alt-cmd-up': 'core:cmd-move-up'
  'alt-cmd-down': 'core:cmd-move-down'
  'alt-cmd-left': 'core:cmd-move-left'
  'alt-cmd-right': 'core:cmd-move-right'

init.coffee

atom.commands.add 'atom-workspace',
  'core:cmd-move-down': () ->
    editor = atom.workspace.getActiveTextEditor()
    editor?.element.setScrollTop editor.element.getScrollTop() + editor.scrollSensitivity
  'core:cmd-move-up': () ->
    editor = atom.workspace.getActiveTextEditor()
    editor?.element.setScrollTop editor.element.getScrollTop() - editor.scrollSensitivity
  'core:cmd-move-right': () ->
    editor = atom.workspace.getActiveTextEditor()
    editor?.element.setScrollLeft editor.element.getScrollLeft() + editor.scrollSensitivity
  'core:cmd-move-left': () ->
    editor = atom.workspace.getActiveTextEditor()
    editor?.element.setScrollLeft editor.element.getScrollLeft() - editor.scrollSensitivity
