我在android 平板电脑上使用chrome 32 （ not 电话），无法弄清楚如何在一个转移中关闭所有打开的选项卡。
I'm using Chrome 32 on an Android tablet (not phone) and just can't figure out how to close all open tabs in one go.
According to this Google Support page, you can't.
You have to close tabs individually, at least on a tablet.
I went to Android's settings, then to apps, then to Chrome, and cleared the data and the cache. When I reopened Chrome, the tabs were all closed. This was done on a Asus Memo 7 tablet. I know it's combersome, but it beats manually closing 100+ tabs.
