Word是学生和职场人士最常用的一款办公软件之一,99.99%的人知道它,但其实,这个软件背后,还有一大批隐藏技能你不知道。
掌握他们,你将开启新世界的大门。
Tab+Enter,在编过号以后,会自动编号段落
Ctrl+D调出字体栏,配合Tab+Enter全键盘操作吧
Ctrl+L左对齐,Ctrl+R右对齐,Ctrl+E居中
Ctrl+F查找,Ctrl+H替换。
然后关于替换,里面又大有学问!
有时候Word文档中有许多多余的空行需要删除,这个时候我们可以完全可以用“查找替换”来轻松解决。
打开“编辑”菜单中的“替换”对话框,把光标定位在“查找内容”输入框中,单击“高级”按钮,选择“特殊字符”中的“段落标记”两次,在输入框中会显示“^P^P”,然后在“替换为”输入框中用上面的方法插入一个“段落标记”(一个“^P”),再按下“全部替换”按钮。
这样多余的空行就会被删除。
Ctrl+Z是撤销,那还原呢?
就是Ctrl+Y,撤销上一步撤销!
比如我输入abc,按一下F4,就会自动再输入一遍abc
