请问用word打化学式中的点（读作合）怎样打

Answer 1

在键盘Tab键正上面这个键，如下图：

　　键盘是最常用也是最主要的输入设备，通过键盘，可以将英文字母、数字、标点符号等输入到计算机中，从而向计算机发出命令、输入数据等。

　　常规键盘具有CapsLock（字母大小写锁定）、NumLock（数字小键盘锁定）、ScrollLock三个指示灯，标志键盘的当前状态。这些指示灯一般位于键盘的右上角，不过有一些键盘如ACER的Ergonomic KB和HP原装键盘采用键帽内置指示灯，这种设计可以更容易的判断键盘当前状态，但工艺相对复杂，所以大部分普通键盘均未采用此项设计。

　　不管键盘形式如何变化基本的按键排列还是保持基本不变，可以分为主键盘区，数字辅助键盘区、F键功能键盘区、控制键区，对于多功能键盘还增添了快捷键区。

　　键盘电路板是整个键盘的控制核心，它位于键盘的内部，主要担任按键扫描识别，编码和传输接口的工作。

　　键帽的反面可见都是键柱塞，直接关系到键盘的寿命，其摩擦系数直接关系到按键的手感。

　　一般键帽的印刷有四种技术：

　　1、 油墨印刷技术;

　　2、激光蚀刻技术;

　　3、二次成型技术;

　　4、热升华印刷技术。
