{ "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" },

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

同时按Ctrl、Shift、P键，出现菜单，搜索编辑器放大。 选择后，字体会变得更大的程度。
