Quickly seek Youtube video playback forwards and backwards by either 3 or 15 seconds.====================================
What This Extension Does
====================================

This tiny and efficient extension helps you easily seek forwards and backwards in Youtube™ videos. If you ever watch long videos and want to seek backwards a little bit so you can see something again, but get frustrated trying to drag that tiny slider just the right amount backwards, this extension is for you! You can either press a couple keys, or click the rewind button to instantly go back!

This extension will add keyboard shortcuts which quickly seek playback forwards or backwards by either 3 or 15 seconds by default, but you can configure this. Additionally, it can also add new buttons to the Youtube™ player which you can click to go backwards or forwards.

====================================
Usage
====================================

1) Load any web page that contains a Youtube video
2) Click the video to make it play
3) The extension will automatically detect the video and add the new seek buttons to it
3) To seek forwards or backwards, you can either click the buttons, or use the Keyboard Controls

Keyboard Controls (windows / linux):
Ctrl + LeftArrow: Seek backwards 3 seconds
Ctrl + RightArrow: Seek forward 3 seconds
Ctrl + SpaceBar: Toggle play / pause
Ctrl + Alt + SpaceBar: Toggle mute / unmute
Ctrl + Shift + LeftArrow: Seek backwards 15 seconds
Ctrl + Shift + RightArrow: Seek forward 15 seconds
Ctrl + Shift + DownArrow: Seek backwards to start
Ctrl + Shift + UpArrow: Seek forward to end (great for skipping advertisements!)

Keyboard Controls (Mac):
Ctrl + Command + LeftArrow: Seek backwards 3 seconds
Ctrl + Command + RightArrow: Seek forward 3 seconds
Ctrl + SpaceBar: Toggle play / pause
Ctrl + Alt + SpaceBar: Toggle mute / unmute
Ctrl + Shift + LeftArrow: Seek backwards 15 seconds
Ctrl + Shift + RightArrow: Seek forward 15 seconds
Ctrl + Shift + DownArrow: Seek backwards to start
Ctrl + Shift + UpArrow: Seek forward to end (great for skipping advertisements!)

For example, it's really easy to hold your ctrl key and then press your left arrow key twice to quickly go back 6 seconds!

You can configure how far forwards and backwards each key takes you via the extension config page. Also, if you don't like the buttons that get added to the Youtube™ player, you can disable some or all of them. To see the config page, click the extension icon on the top-right of your browser, then select "options", just like on any other extension. Alternatively, goto the chrome://extensions url, click the "Details" button for this extension, then click "Extension Options".

TIP: You can skip through some advertisements by just fast forwarding! Try using the "Seek forward to end" keyboard control. You can also rewind the ad, if you like.

Hidden Feature:
Note that the keyboard controls work properly even when you're on a non-youtube.com website which embeds the video into their webpage. When using keyboard controls, you don't need to give the youtube video "mouse focus" by clicking on it, which allows you to freely interact with the parent web page without worrying about losing mouse focus due to clicking something else. This can be handy, for example, if you've scrolled to the bottom of the page to read comments, and suddenly wish to rewind or pause the video without having to scroll back to the top - just use the keyboard controls. While youtube does have their own keyboard control to pause the video (the space bar), it only works on non youtube.com pages when the video currently has "mouse focus". This extension offers its own pause control (Ctrl + SpaceBar) which works without the video needing focus. The same goes for all the keyboard controls - they all work without needing the player to have focus! The browser tab does need focus, however.

Limitation:
-The GUI buttons can only be added to the Youtube™ player if there's enough width - small players are a problem here. If you maximize the player, the buttons should show up, or you can always just use the keyboard controls.
