Keyboard shortcuts inconsistent with browser defaults #19

Since Shift+Enter hasn't been working (#13) and Ctrl+Enter (and Ctrl+Shift+Enter) have not yet been released (#16), it may be a good opportunity to take a second to think about consistency before it comes back to bite us. The defaults in Chrome/Opera are:

• Shift+Click to open a new window
• Ctrl+Click to open a background tab
• Shift+Ctrl+Click to open a foreground tab

This extension will have

• Shift+Ctrl+Enter to open a new window
• Ctrl+Enter to open a background tab
• Shift+Enter to open a foreground tab

We should consider using the same modifiers for the same actions in the browser and the extension.

Pro:

• Prevent the constant annoyance of remembering which has which shortcuts

Cons:

• The extensions's modifiers are much better than the browser's (you open tabs much more often than you open windows)
• It doesn't really matter anyway: once the shortcuts are fixed I for one will strive to never use the mouse again!
