KPDF
KPDF——查看打印 PDF 文件
KPDF 为 KDE3 编写，是最早能查看和打印 PDF 文件的自由开源应用程序之一。
Features Highlights
- Thumbnail panel for ease of navigation
- View in Fit-to-screen or Fit-to-width modes, changed with a single click
- Multi-mode searching - the usual facility to search from the Find dialog is there of course, but you can also use the filter box above the thumbnails to find pages containing that text. Typing "/" then some text will start type-ahead searching
- Auto-scrolling - activate by the default keys (Shift+Up and Shift+Down) or by shortcut keys to your taste.
