Description of the Issue

There seems to be an undocumented and unconfigurable keyboard shortcut CTRL+SHIFT+D that inserts the invisible control character EOT at cursor position. This breaks scripts with obscure error messages since control character are usually set to invisible.

Tested on 2 different installations with different addons on Windows 10 and Windows 11.

Steps To Reproduce

1. Run latest Notepad++ and create a new sheet
2. Ensure that View → Show Symbol → Show Control Characters & Unicode EOL is disabled
3. Press the keys CTRL+SHIFT+D, note that is seems as if this had no effect
4. Enable the setting from step 2
5. Note that the control character EOT is displayed as first character
6. Open Settings → Shortcut Mapper... and use "CTRL+SHIFT" as Filter expression
7. Note that it seems that CTRL+SHIFT+D seems unassigned while it's clearly not

Current Behavior

An invisible control character is inserted by an undocumented keyboard shortcut.

Expected Behavior

Either the keyboard shortcut should not exist or it should be configurarble via the settings dialog.
