You can also use the following to find tab chars directly in Find without having to play with the PreserveEntities settings at all using Regex mode:

\x{09}

That will look for a specific utf-8 hex char

or the more traditional

\t

But search mode most be Regex for those to work. Normal mode removes the significance of the leading "\"

If you copy a tab from some text editor, you can actually use Normal mode and just paste the copied tab into the Find field and that would work too.

Typing a tab using the keyboard directly into the Find field will not work as tab is used to switch input fields in Qt for people who prefer/need keyboard accessibility instead of the mouse to select a field.
