根据版本1.2的更新日志，增加了新的命令，可以放大和缩小字体，但可以放大和缩小整个UI。

更新日志:https://code.visualstudio.com/updates/v1_24 # _font-zoom-commands

使用以下键绑定替换默认的全局缩放动作:

在macOS:

{ "key": "cmd+numpad_add",      "command": "editor.action.fontZoomIn" },
{ "key": "shift+cmd+=",         "command": "editor.action.fontZoomIn" },
{ "key": "cmd+=",               "command": "editor.action.fontZoomIn" },
{ "key": "cmd+numpad_subtract", "command": "editor.action.fontZoomOut" },
{ "key": "shift+cmd+-",         "command": "editor.action.fontZoomOut" },
{ "key": "cmd+-",               "command": "editor.action.fontZoomOut" },
{ "key": "cmd+numpad0",         "command": "editor.action.fontZoomReset" },
{ "key": "cmd+0",               "command": "editor.action.fontZoomReset" },

在Windows和Linux上:

{ "key": "ctrl+numpad_add",      "command": "editor.action.fontZoomIn" },
{ "key": "shift+ctrl+=",         "command": "editor.action.fontZoomIn" },
{ "key": "ctrl+=",               "command": "editor.action.fontZoomIn" },
{ "key": "ctrl+numpad_subtract", "command": "editor.action.fontZoomOut" },
{ "key": "shift+ctrl+-",         "command": "editor.action.fontZoomOut" },
{ "key": "ctrl+-",               "command": "editor.action.fontZoomOut" },
{ "key": "ctrl+numpad0",         "command": "editor.action.fontZoomReset" },
{ "key": "ctrl+0",               "command": "editor.action.fontZoomReset" },

按Ctrl并使用鼠标滚轮放大或缩小。

在Visual Studio Code中，通过按Ctrl+和Ctrl-可以改变IDE的整体字体大小。 这比在每个会话中更改设置更快。

As of mid 2017 To quickly get to the settings files press ctrl + shift + p and enter settings, there you will find the user settings and the workspace settings, be aware that the workspace settings will override the user settings, so it's better to use the latter directly to make it a global change (workspace settings will create a folder in your project root), from there you will have the option to add the option "editor.fontSize": 14 to your settings as a quick suggestion, but you can do it yourself and change the value to your preferred font size.

总结一下:

CTRL + shift + p 选择“用户设置” 添加”编辑器。字形大小”:14

您可以从“视图”菜单中放大和缩小整个用户界面。

现在我使用的是1.21.1版本，在视图菜单中，你可以得到放大和缩小选项，这是第二和第三个最后的选项。 你可以使用Ctrl + +和Ctrl + -。

您可以通过选择“重置缩放”选项随时重置缩放。

尝试使用以下用户设置的组合:

{
  "editor.fontSize": 18,
  "window.zoomLevel": 1.5,
}
