        電腦(Computer)是一種利用電子學原理根據一系列指令來對數據進行處理的設備。計算機由運算邏輯單元、控制器、輸入和輸出設備、記憶單元五大單元組成,以二進制為計算機基本單位。

        電腦入門,F1到F12有什么用

        F1~F12通常稱為功能鍵,其中F指的是Function功能的意思,說明F1~F12是12個功能鍵。每一個電腦鍵盤標配都是頂端都有F1~F12一排按鍵。

        我估計全部掌握的人還真不算多,今天高手君就給大家普及一下F1~F12鍵在日常Windows系統中的功能和使用。

        注意,僅限臺式機或者筆記本的外接鍵盤。(部分筆記本自帶鍵盤F1~F12被賦予了其他功能,不再此文討論之列)。

        F1:幫助鍵。

        當碰到一個程序或一個步驟不明白使用方法的時候,按下F1可以查詢該程序的幫助信息。但通常情況下我們按下F1按鈕調用的都是Windows系統自帶的幫助信息,個別應用程序設置了F1調用自帶幫助信息。

        如Wps中按下F1就可以看到程序自帶的幫助。

        替代:點擊文件->幫助的操作

        F2:重命名

        這個鍵大家可能都比較熟悉,選中一個磁盤、文件夾或文件,按下F2就可以給選擇的磁盤、文件夾或文件重新命名。

        替代了選中->右鍵->重命名的操作。

        F3:搜索按鈕

        在電腦的磁盤、資源管理器或文件夾下中需要查找某個文件時,按下F3光標就直接轉入搜索欄,可以進行區域搜索。

        F4:瀏覽器網址列表

        F4是瀏覽器專用功能鍵,打開瀏覽器,按下F4可以直接查詢我們曾入輸入的網頁地址,相當于旁邊的那個下拉按鈕。

        F5:刷新

        這應該是大家使用最頻繁的一個功能鍵,用于桌面或瀏覽器中,使內容重新載入。

        在非瀏覽器中相當于右鍵->刷新,瀏覽器中相當于刷新按鈕。

        F6:瀏覽器地址欄定位

        與F4類似,一般專用于瀏覽器中,但是按下F6只讓光標定位于地址欄輸入框,而不會顯示歷史輸入記錄。

        F7:在“命令提示符”調用歷史指令

        F7在Windows界面中沒有效果,專用于Windows中的“命令提示符”中,按下F7可以直接調用我們前面鍵入的指令。

        F8:啟動高級菜單

        F8用于電腦啟動,調用啟動的高級菜單。當我們的電腦啟動時,快速按下F8,可以進入啟動的高級菜單選項。這個大家應該都比較熟悉了。

        F9:無用無用無用

        F9基本上不上的一個功能鍵,我僅僅知道在Windows Media Player中可以調低音量,在outlook中可以收發郵件,可以說基本無用。

        F10:需要與Shift組合使用,調用鼠標右鍵

        F10不能單獨使用,需要與Shift組合使用,按下“Shift+F10”=按下鼠標右鍵。單獨使用在Windows Media Player中可以提高音量=沒用

        F11:瀏覽器進入或退出全屏

        F11又一個瀏覽器專用功能鍵挺常用的,可以是瀏覽器進入或退出全屏狀態。

        F12:另存為。。。和開發人員工具

        在應用程序中,如Word、Excel等程序中按F12可以直接調出另存為。。。。菜單;在瀏覽器中按F12可以調出“開發人員工具”。
