Description of the Issue

In Notepad++ v8.9.1 on Windows 11, the keyboard shortcuts for switching documents do not match their labels when MRU behavior is enabled. Pressing Ctrl + Tab as a shortcut for "switch to previous document" doesn't switch to the previous document it switches to different documents erratically. To achieve a standard "back-and-forth" toggle between the two most recently used tabs, the user must incorrectly assign Ctrl + Tab to "Switch to next document" rather than "Switch to previous document."

Steps To Reproduce

1. Open 4 documents (Doc 1, 2, 3, 4).
2. Go to Settings > Preferences > MISC. and ensure Enable MRU behavior is checked.
3. Manually click Doc 2, then manually click Doc 4.
4. Press the default shortcut for Switch to previous document (assigned to Ctrl + Shift + Tab).

Current Behavior

It does not reliably return to Doc 2; rather it erratically cycles through the document list instead.

Expected Behavior

The label Switch to previous document should be the action that returns the user to the most recently viewed tab in MRU mode.

Debug Information

Notepad++ v8.9.1 (64-bit)
OS: Windows 11

Anything else?

Workaround: Go to Shortcut Mapper and reassign Ctrl + Tab to "Switch to Next Document"
Result of Workaround: Pressing Ctrl + Tab now correctly switches to the previous document and toggles back and forth between Doc 2 and Doc 4.
