CLUT: Cycle Last Used Tabs

Cycle through last used Chrome tabs using keyboard shortcut.This extension tries to mimic the ALT+TAB behavior from Windows(or Command+TAB in Mac) to allow to switch between open tabs in a Most Recently Used fashion.
It remembers the order in which you switched tabs (made a tab active) and it updates its records so that you can switch to the recently used ones quickly.

Note: Sometimes after updating the extension the keyboard shortcut settings get reset. Hence you might want to set the desired key board shortcuts again in the keyboard shortcut settings in the Chrome Extensions page.


Please rate and comment.

The project is made open source in GitHub:
https://github.com/harshayburadkar/clut-chrome-extension.git

Default Keys*:
ALT+W: Quick switch
ALT + S: Normal switch
ALT + Shift + S: Normal switch (in opposite direction)
*Keys can be changed in keyboard shortcut settings on the Chrome extensions page.



=Quick switch=:
Use for rapid switching to last tab (by pressing once) or to the second to last used tab(by pressing rapidly twice) and so on.

=Normal switch=:
Use when you want to look for a tab recently used but when you would want to go in a slower pace (needing to glimpse for a bit to see if it is the page you need)

Most other extensions meant to accomplish the same thing don’t work well since there are some limitations/difficulties in the Chrome API. This extension uses some basic algorithms and timers of intervals between key presses to get over these problems. That is the reason there is separate keys for quick and slower switches with different timer settings.

Features:
* Can cycle through ALL open tabs from all Chrome windows in a most recently used order
* Extension DOES NOT need access to any of your visited website's data
* Can work through tabs across different Chrome windows
* Snappy and fast switches


FAQ:

- Why are there two sets of shortcuts one for quick switch and one for a slower switch. Isn’t it possible to simplify like ALT+TAB behavior ?
A: There are some restrictions in Chrome API which makes it difficult to implement this feature in the most natural way. The intention was to make this extension work as close to Alt+Tab in Windows (or Cmd+Tab for Mac). Unfortunately due to these limitations though, this extension relies on time intervals in between your key presses. That is the reason there is a concept of quick switch (faster timer) and a normal switch (slower timer).

- Where can I change the shortcut key for switching tabs ?
A: To change shortcut, go to the Extensions pane in your Chrome browser and in the bottom of the list of extensions find the Keyboard Shortcuts link. You can change keyboard shortcuts of your installed extensions and apps here.
Note: Few shortcuts may be not allowed to be set by Chrome if Chrome itself uses that shortcut or the shortcut is needed for system level operations.
