Hotkeys

HOW TO USE:
After installation, works only in NEW or RELOADED tabs. Those tabs must be WEB PAGES too. Click on the icon in location bar to disable/enable for a page.
To change options, go to Extensions and click on Options for this extension. Or right-click on icon(if present) in location bar and click Options.

LIMITATIONS:
This extension works by plugging JavaScript into pages you load. As such, it cannot change system settings like disabling default hotkeys of Chrome. It also works only when you are in tabs with actual web pages, and not every web page works (see your luck :P). Finally, some shortcut combinations may not work. Right now, these are limitations that cannot be overcome.

CHANGES:
0.13 had a bug with saving options. Fixed now.
0.14 had some options not working. Fixed now.
0.20 change the way the blocklist works
Recent changes made because Google required developers to make some changes. As it has been so long since I worked on extensions, I might miss out some things. I won't be maintaining this extension much, though.
0.21 remove host permission

DESCRIPTION:
Enable/disable hotkeys and change shortcuts for browser actions. Default keys are from Gamer's Control.

You can enable/disable hotkeys temporarily by clicking on the icon in the omnibar.

Blocklist interface is only for advanced users. You can specify the URL where the hotkeys will be disabled.

After installation, it will only work on new or reloaded tabs.

AutoControl seems like a better extension (this is not an endorsement and I've not used it myself)
