Add CTRL+ArrowLeft and CTRL+ArrowRight for generic next/previous page. It will click the last found link/button whose text starts/ends with e.g. "Next", "Prev", or "Previous".
目前为
The link/button text more specifically, are those which starts with (non case sesitive) "Next", "Prev", "Previous"; or ends with "Prev", "Previous", "Next". e.g. "Next", "> Next", "Next Page", "Prev", "< Prev", "< Previous", etc. but not "< Prev Page" because the word "prev" or "previous" is not at the start/end of text.
This script doesn't take into account of links whose contents is an image rather than text, or whose text is a CSS text contents.
If next/previous navigation link is specified in the HTML metadata, it will be used as a priority.
