我猜你说的是快捷键ctrl+1选择第一个标签，ctrl+2选择第二个标签等？
1.打开keybindings json文件（cmd+shift+p，输入Preferences: Open Keyboard Shortcuts (JSON)）。
1.将这些添加到文件的末尾：

{ "key": "cmd+1", "command": "workbench.action.openEditorAtIndex1" },
{ "key": "cmd+2", "command": "workbench.action.openEditorAtIndex2" },
{ "key": "cmd+3", "command": "workbench.action.openEditorAtIndex3" },
{ "key": "cmd+4", "command": "workbench.action.openEditorAtIndex4" },
{ "key": "cmd+5", "command": "workbench.action.openEditorAtIndex5" },
{ "key": "cmd+6", "command": "workbench.action.openEditorAtIndex6" },
{ "key": "cmd+7", "command": "workbench.action.openEditorAtIndex7" },
{ "key": "cmd+8", "command": "workbench.action.openEditorAtIndex8" },
{ "key": "cmd+9", "command": "workbench.action.openEditorAtIndex9" }

字符串
如果你还想修改ctrl+tab和ctrl+shift+tab来选择上一个/下一个标签，你也可以添加这些（但请记住，它们可能会与mac快捷方式冲突）：

{ "key": "cmd+tab",              "command": "workbench.action.quickOpenPreviousRecentlyUsedEditorInGroup",
 "when": "!activeEditorGroupEmpty" },
{ "key": "cmd+shift+tab",        "command": "workbench.action.quickOpenNavigatePreviousInEditorPicker",
 "when": "inEditorsPicker && inQuickOpen" },
