Description Sciuriware 2017-05-17 18:13:08 UTC
In order to toggle between INSERT mode and OVERWRITE mode the Insert key is listed (for Microsoft). Such a key does not exist on the Mac keyboard.
Please provide another keystroke for macOS (Sierra).

Additionally: the Status bar shows nothing for INSERT mode; please have that word
put there, because when blank, the proper field in the Status bar is impossible
to see, let alone to click.

@Heiko, I thought you might be interested in this issue...
Comment 4 Heiko Tietze 2019-01-30 17:34:17 UTC
Apple has no Insert key and apparently no overtype mode. Microsoft provides an option in a configuration dialog to toggle insert/override. 

We could implement a key additional to KEY_INSERT at editeng.cxx #1259. Checking the world wide wisdom I'd say FN+Enter is the most often cited variant (FN+backspace is the common delete, so it's somewhat natural). However, this key would be hard-coded and wont be customizable. And to raise the difficulty we do not have a function key defined yet (think it's possible when we restrict it to macOS).

(Adding UX although it's a qualified easyhack to gather input. If a volunteer wants to take this we can just go ahead.)

I would suggest to take advantage of the CMD key rather, as it is quite
common on macOS. So it could be CMD/Enter to toggle.

   /** (non-Javadoc)
    * @see java.awt.event.ActionListener#actionPerformed(java.awt.event.ActionEvent)
    * @param a action event.
   public void actionPerformed(ActionEvent a)
      Object o = a.getSource();
      int m = a.getModifiers();
      boolean metaPressed = (m & ActionEvent.META_MASK) != 0; // Defined in ActionEvent.java


      if(o == ENTER_KEY)
            toggleOverstrike();  // Or such

Btw.: I think that showing the overstrike status has priority,
as we can use the mouse already.

Cmd+Enter is used for manual page break. And I'd be careful with those easy to enable keys as users might press it accidentally not knowing how to get back.
Comment 7 Sciuriware 2019-01-30 18:50:04 UTC
You may be right. Well, in ECLIPSE it is Ctrl+CMD+O.
And .... I'll be just happy with the word "Insert" down below.
Remember that the word "Overwrite" shows there already.
Comment 8 Heiko Tietze 2019-01-31 11:33:09 UTC
I asked a couple of people at the LibreOffice hackfest and none uses the overwrite mode. There is a tendency to refuse the shortcut but we better run a poll to have this decision based on a larger number of macOS users. Here it is https://design.blog.documentfoundation.org/2019/01/31/overwrite-on-macos/
Comment 9 Sciuriware 2019-01-31 11:45:58 UTC
OK, I give in: drop the shortcut; please make the status (Insert/Overwrite)
