Find dialog doesn't allow to select a different tab easily via the keyboard

Steps to Reproduce the Issue

1. Open the find dialog
2. The first tab is active
3. Try to access the Tab "Mark" just with the keyboard

Expected Behavior

I want to use F6, or Shift+F6, Ctrl+PageUp, Ctrl+PageDown, or press Alt+Hotkey to activate another tab page in the Find Dialog
This are standard hotkey in Windows!

Or Ctrl+Number to access the first, second, third tab.

Actual Behavior

The onyl way is to press Shift+Tab, move the focus to the tab, press right or left.
The focus turns back onto the first control in the tab.
I have to repeat Shift+Tab, Right.

Comment

The keyboard interface of Notepad++ is horrible and!
