137842 - up/down arrow in quoted text moves caret too far (x coord not maintained)

Status: VERIFIED WORKSFORME

(Core :: DOM: Selection, defect)

Description

[xolaware.llc]

From Bugzilla Helper:
User-Agent: Mozilla/4.79 (Macintosh; U; PPC)
BuildID:    2002041603

there are a few problems using the typical keys to navigate in message 
composition.

1) option-left_arrow properly goes back a word at a time, but
   option-right_arrow treats every space between words as a word and
   cannot navigate past most punctuation.

2) if in the middle of quoted text, if using the up-arrow, the cursor
   always jumps to the end of the line, where it should always attempt
   to end up in the same column on the preceding line.

3) same problem for down-arrow and the next line.

4) attempting to introduce new lines in quoted text in order to respond
   point-by-point to the quoted message sometimes enters too many
   newlines, and other times causes the cursor to appear in one place
   but the entry-point/deletion-point to show up elsewhere when text
   is typed in or deleted
 

Reproducible: Always
Steps to Reproduce:
1. open "Mail & Newsgroups" (cmd-2)
2. choose a message and hit "Reply"
3. enter a paragraph or two of your own text (copy the description for
   this bug, for example).
4a. try option-right_arrow and option_left_arrow in the text you
    entered or in the quoted text
4b. try using the up-arrow and down-arrow to navigate through the
    quoted text
4c. try creating space within the quoted text by hitting Return one
    time somewhere in the middle of the quoted text (at the beginning
    of one of the quoted text lines is fine


Actual Results:
4a. option-right_arrow stops at every space and will not go forward
    past punctuation
4b. cursor ends up at end of each line of quoted text, no matter where
    the cursor was in the line prior to hitting the arrow
4c. multiple new lines are entered, and sometimes the next attempt to
    edit text leaves the cursor on the new line but deletes the
    characters on the previous line


Expected Results:
4a. option-right_arrow should skip over each space and navigate past
    punctuation in the same manner that option-left_arrow does going
    backward in the text
4b. the cursor should be on the same column as the previous line, if
    possible.  best would be if the cursor remained at the same column
    for multiple lines, even if intervening lines did not have that
    many columns.
4c. entering newlines or new text in the middle of quoted text should
    behave just like non-quoted text

issue 1 is covered in other bugs already (bug 121123? I forget; sorry)
issues 2 and 3 can be covered in this bug
issue 4 should be filed as a new bug (Component = Editor:Core)

This WorksForMe using Mac/2002072203. Up and down arrow actions maintain their x-coordinate, 
unless the line is too short, in which case the cursor is placed at end-of-line. If the cursor is then moved 
back onto a long-enough line, the original x-coordinate is resumed.

[e-mail], do you concur?
