            Bug ID: 453133
           Summary: HOME and END keys show non-standard behavior in
                    Dolphin when renaming files
           Product: dolphin
           Version: 21.12.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org

  Target Milestone: ---

When renaming a file with a long name (more than one line) in Dolphin, the HOME
and END keys show a non-standard behavior.  Previously, the HOME key would send
the cursor to the beginning of the current line and END key would send the
cursor to the end of the current line, which is the expected behavior. Now, the
HOME key sends the cursor to the beginning of the file name and the END key
sends the cursor to the end of the file name, even across multiple lines, which
is non-standard, different from these keys' behavior in any other GUI
application. In any GUI application, the HOME key sends the cursor to the
beginning of the current line and the END key sends the cursor to the end of
the current line, not to the beginning or the end of the current paragraph.
That's what the average user expects.
Because of this non-standard behavior in Dolphin, if the user wants to go to
the beginning or to the end of the current line, he must press a side arrow key
a lot of times to get there. With the standard behavior, he could just press a
single key to go to the beginning or to the end of the current line, or press
the UP/DOWN arrow keys just a few times and then HOME or END to go to the
beginning or to the end of the file name. 
The current Dolphin's behavior makes it more difficult and time-consuming to
navigate through a long file name.

STEPS TO REPRODUCE
1. Select a file with a long name (multiple lines)
2. Press F2 to rename it
3. Press the LEFT arrow to send the cursor to the beginning of the file name
4. Press the END key

OBSERVED RESULT
The cursor is sent to the end of the file name, several lines below where it
was

EXPECTED RESULT
The cursor should have been sent to the end of the first line of the file's
name
