The Page Up and Page Down buttons (sometimes abbreviated as PgUp and PgDn ) are the two keys commonly found on computer keyboards.
Both of these buttons are mainly used for scrolling up or down in the document, but the scrolling distance varies between different applications. In word processors, for example, they can jump by physically imitated pages or by a screen display that may only display a portion of a single page or multiple pages at once depending on the zoom factor. In the case when the document is shorter than one screen, : 1px solid #aaa; -moz-border-radius: 0.2em; -webkit-border-radius: 0.2em; border-radius: 0.2em; -moz-box-shadow: 0.1em 0.1em 0.2em rgba (0,0,0,0.1); -webkit-box-shadow: 0.1em 0.1em 0.2em rgba (0.0, 0,0.1); box-shadow: 0.1em 0.1em 0.2em rgba (0,0,0,0.1); background-color: # f9f9f9; background-image: -moz-linear-gradient (top, #eee, # f9f9f9, #eee); background-image: -o-linear-gradient (top, #eee, # f9f9f9, #eee); background-image: -webkit-linear-gradient (top, #eee, # f9f9f9, # eee); background-image: linear-gradient (down, #eee, # f9f9f9, #eee); padding: 0.1em 0.3em; font-family: inherit; font-size: 0.85em; "> Page Up and Page Down often has no visible effect at all.
The operating system is different whether the button (pressed without modifiers) just moves the display - ie. in Mac OS X - or also the paste - ie. in Microsoft Windows. In the right-to-left setting, PgUp will move well to up or right (not left) and PgDn will move down or left (not right) button dubbed previous page and next page , accordingly.
Tombol panah dan roda gulir juga dapat digunakan untuk menggulir dokumen, meskipun biasanya dengan jarak inkremental yang lebih kecil. Digunakan bersama dengan kunci pengubah, seperti Alt , ? Pilih , ^ Ctrl atau kombinasinya, mereka dapat bertindak sama dengan tombol Halaman.
Di sebagian besar sistem operasi, jika tombol Page Up atau Page Down ditekan bersama dengan ? Geser tombol dalam teks yang dapat diedit, semua teks yang digulir akan disorot.
Dalam beberapa aplikasi, Page Up dan Halaman Bawah berperilaku berbeda dalam navigasi caret (diubah dengan F7 fungsi kunci di Windows). Untuk mengklaim 30% orang, tombol paging memindahkan teks ke arah yang berlawanan dengan apa yang mereka temukan alami, dan perangkat lunak dapat berisi pengaturan untuk membalikkan pengoperasian tombol-tombol ini untuk mengakomodasi itu.
In August 2008, Microsoft received a patent # 7,415,666 for the function of two keys - Page Up & amp; Page down.
