A powerful word highlight script that can do more than highlight.

Intro

Enhanced word highlight (Ewh) is the enhanced version of "word highlight" script (see more in "Credit"). Its features include:

Highlight search keywords: Automatically highlight search keywords in result pages of Google, Bing, etc., as well as in the pages opened from search result links;
Inheriting highlight: Highlighted keywords will also be auto-highlighted in the same session, for example, subsequent pages in the same browser tab;
Manual highlight: Pressing "Alt-/" key combination, selected text will be instantly highlighted; otherwise, an keyword inputbox will show for you to input keywords (support regular expression) for highlight;
Highlight map: It can show the position of highlighted keywords and let you quickly navigate to where they are;
Keyword button: On a keyword button, clicking left or right mouse buttons or scrolling will instantly navigate to the keyword's highlight positions; clicking the checkbox at the upper-right corner can toggle its highlight status;
Control buttons: Clicking the "L" button to toggle keyword set's locking status; clicking the "O" button to toggle all keyword's highlight status; clicking the "E" button to edit keyword set; clicking the "X" button to close Ewh;
Refresh highlight automatically as the webpage changes;
Plenty options to fit your usage demand;
More highlight color set for your selection.

Usage outline

Please use space to seperate each keyword for highlight; East Asian characters will be automatically seperated from other characters by default (changable in Advanced Config).
If you have to highlight a keyword containing space, plus symbol etc., you should add double quotation marks around the keyword.
If you want to highlight regular expressions, please input through keyword inputbox, with one complete expression at one time.
Default key combination shortcut:
- Alt-/ (the left slash key):
  - (when text selected outside of any inputbox) highlight selected text,
  - (when an inputbox is in focus) highlight text in the inputbox,
  - (no selected text and no inputbox in focus) pop out keyword inputbox;
- Alt-, (comma key): toggle all keywords highlight status;
- Alt-.(dot key): toggle keyword editing status;
- Ctrl-Alt-/ : exit Ewh in current session;
- r key: refresh highlight manually;
- n key: sequentially navigate to each highlight of any keyword in the page;
- Shift-n: do the similar job as n key but in backward sequence.
After exiting Ewh in a session, subsequent search keywords or locked keywords will still be highlighted in this session.
When some keywords are locked for highlight, any page refreshed afterward will priorly highlight locked keywords; editing keywords will not affect the locking status if "L" button is not clicked; the locking status can only be turned off by clicking the "L" button.
If you use any Greasemonkey compatible script manager, you can find a menu item "Advanced Config" of Ewh in its menu. You can click this menu item and modify Ewh config in the pop-up dialog to your preference.
Issues to be noticed:
- You are recommended to use Tampermonkey addon / extension to gain full experience of Ewh.
- Some autopaging or readability tools will function in a way that would break the continuity of a session, thus making highlight to vanish or unable to auto-refresh. If so, you will have to manually refresh highlight or re-input keywords for highlight.
- Under Firefox, its safety mechanism forbid some pages to apply some third-party script functions, letting Ewh unable to run within.
