Enter键就等于左键.1、检查“控制面板”中“鼠标”的设置情况。特别是“右手习惯”和“左手习惯”是否选错。“文件和文件夹”选项中是否为“单击打开一个项目”?再者双击速度是否合适(最好在中间)。 2、鼠标用久了可能左键已损坏。那只好更换一只新鼠标啦。 3、用杀毒软件杀一下病毒,看是否是木马之类的东东在作怪哦。(最好用木马专杀一类的软件更合适些)你可以按alt+shift+numlock组合键,然后再按一下numlock,你就可以使用了,按一下小键盘的123456789,看看有什么情况,5就可以代替鼠标左键。挨着ctrl的那个(不是菜单键),就可以代替鼠标右键。Enter键就等于左键光用键盘的话,就是四个箭头代替鼠标上下左右移动,Enter就是快捷键吧Painter hotkey 快捷键 Painter快捷键 Tool Name Keyboard Shortcut Magnifier M Grabber G Rotate Page E Perspective .
