^{⚙️ AdGuard version: 7.13 nightly 12 (build 4262, CL 1.11.88)
💻 OS version: Windows 10 Pro 22H2 (OS Build 19045.2965)}

👋 Steps to reproduce

1. Right-click on the AdGuard systray icon > Tools > Filter editor.
2. Using the advanced filter editor, add this without saving:

example.org##h1
example.org##p
example.org##a

3. Put your text cursor at the end of the second line (i.e. after the p).
4. Press Shift + Home to select the line.
5. Press the Left arrow key and type www..

Expected behavior

example.org##h1
www.example.org##p
example.org##a

Actual behavior

example.org##h1www.
example.org##p
example.org##a

Similar problem with the other way around, i.e.:

• put your text cursor at the end of the second line → put your text cursor at the beginning of the second line;
• Shift + Home → Shift + End;
• Left arrow key → Right arrow key;
• unexpectedly arrive at the end of the previous line ✖️ → unexpectedly arrive at the beginning of the next line. ✖️

ℹ️ Expected behavior is the typical result of editors.
↬ Tested on: VS Code, Notepad++, Notepad. Plus on a textarea in both Firefox (113.0.1) and Chrome (113.0.5672.127).

@contribucious Hi!

This is not a bug. However, this is an interesting idea and we will put it in a backlog for review and implementation.

@AlexandrPkhm Hello. OK, great! 👍

Not a bug as such, but unexpected behavior, rather, indeed.

↬ Personally, through a lot of software used, this is the first time I see this particular behavior I think. As said in Additional information, every major code/text editor I use always puts the text cursor to the left of the selection when the Left key is pressed, not one character before (which, in this case, comes to the end of the previous line and is unexpected IMHO). So, thanks! ✌️
