Shortcut Manager

Customize shortcut keys; Assign any Javascript code or browser actions to any key strokes.

You can change the browser default shortcut keys, and assign any bookmarklets or Javascript action to your hotkeys. It works as Keyconfig on Firefox.
Example actions:
 - Tabs: "Left Tab", "Upper directory", "Close right tabs", "Open your favorite page",...
 - Page: "Scroll up/down", "Insert your signature",...
 - Special: "Screen Capture"
 - Custom: Execute any Bookmarklets or Javascript code!
You can also import or export your settings so you can share it with others.
