Updated: Cannot produce special characters using AltGr due to RTE keyboard shortcuts

After upgrading to Confluence 3.4, the Rich Text Editor breaks standard keyboard functionality.

How: By capturing AltGr + [1 - 7, Q] (which produce different special characters on European keyboard layouts) as Ctrl + Alt + [1 - 7, Q] (which formats text as heading, quote or paragraph).

Below are examples of only a few signs that cannot be produced due to this bug. They may apply to more than one layout and many more can be found for instance on Wikipedia.

Examples:
AltGr + 2 produces at sign (@) (FI)
AltGr + 3 produces pound sign (£) (FI)
AltGr + 4 produces dollar sign ($) (FI)
AltGr + 7 produces left curly brace ({) (FI)
AltGr + Q produces at sign (@) (IS, DE)

This behavior is changed from Confluence 3.3 where Ctrl + Alt + number combinations were not mapped to heading formatting shortcuts; only Ctrl + number combinations were.

To reproduce one of these issues:

• Change the keyboard layout to Finnish
• Open the Rich Text Editor
• Type some text
• Press AltGr+2, which should produce an at sign (@)

Instead the text changes to a level 2 heading.

This behavior is breaking our editing experience as the only way to produce these special characters is to switch to markup mode. This breaks the editing workflow. The bug is also not readily apparent and may confuse a large portion of users.
