434373 - keystrokes for "beggining of line" and "end of line" don't work properly on some textareas

Status: RESOLVED DUPLICATE of bug 342564

(Firefox :: General, defect)

Description

[david muñoz]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; es-ES; rv:1.9) Gecko/2008051202 Firefox/3.0
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; es-ES; rv:1.9) Gecko/2008051202 Firefox/3.0

In Mac OS X, the key combination for "beggining of line" is COMMAND-LEFT, and for "end of line" is COMMAND-RIGHT. These key combinations are the same for "go back" and "go forward" in history.

In some cases, when editing a text area, if the user types these combinations, the browser goes back or forward. Sometimes the text entered in the text area is lost.


Reproducible: Always

Steps to Reproduce:
1. Log in any vBulletin and open any thread
2. At the bottom of the page, click in the Reply text area
3. Write some text
4. Type COMMAND-LEFT to go to the beginning of the text line

Actual Results:  
Instead of moving the text cursor to the beginning of the text line, the browser goes back to the last visited page (goes back in history)

Expected Results:  
The text cursor should move to the beginning of the text line. 

I have experienced this behaviour in vBulletin forums. I think that in these forums the textarea is controlled by javascript; when using a plain textarea (with no javascript), the behaviour is exactly whait it is expected.

I'm guessing these vBulletin fields are rich-text input fields (designMode or contenteditable) rather than ordinary textareas, which causes bug 342564 to surface.
