每周一次，我们都会在小费盒里拿出一些聪明的建议与大家分享。本周我们将研究如何立即冷却你的热车，提高你的谷歌搜索结果与自动同义词，并扩展你的安卓键盘。

通过打开和关闭车门来冷却热的汽车

马克用这种冷静技巧写道：

I know cooling down your car is not exactly a technological tip and probably not your bag (so I don’t mind if you don’t post this) but it’s been so freaking hot I had to send it in. I found this video browsing Reddit the other day and tried it out on my own car. It worked so well! Here’s the trick: when your car is hot from being in the sun you can cool it down by rolling down one window and then, on the opposite side, open and close the car door around a half-dozen times. It pumps cooler air in from outside the car like a big set of bellows. It’s awesome. I couldn’t believe how fast it cooled the car down.

我们很乐意破例，因为天气非常热。本周，美国中西部地区的露点已经上升到如此之高，以至于明尼苏达州的一些地区和亚马逊一样潮湿。任何能让人们在热浪中降温的方法都值得分享！谢谢马克！

用同义词搜索google

史蒂夫用一个聪明的搜索技巧写了进去：

Lots of people know that you can modify your Google search with operators like the + and – symbol to force Google to search for or remove a specific word from the query. Did you know that you can search for synonyms? If you put a tilde (the ~ symbol) in front of a search term it will tell Google to also search for synonyms. The query ~cheap shoes for example gives results as though you had searched for cheap shoes, inexpensive shoes, affordable shoes, etc. It’s really handy when you want to broaden your search results without getting too far away from your original search.

小费不错，史蒂夫！我们本以为自己是谷歌的忍者，但用tilde强制同义词搜索是我们以前从未使用过的一个技巧。很好的发现。

向上滑动以获得更多的android键盘空间

Angela writes in with a handy way to work faster on an Android keyboard. She writes:

I found this by accident while typing furiously on my phone the other day. On my Android phone if I swipe up while using the keyboard the keyboard automatically extends two rows and makes the punctuation and numbers visible. It chews up a little screen space but it makes typing so much easier!

没有多少人知道安吉拉的这一特点。如果你有android2.2或更高版本，并且使用默认键盘，那么只需轻扫一下就可以使用宽敞的键盘。谢谢你的来信！
