How to convert Ctrl (any letter) to «Ctrl (any letter)»?

I need like this:

Ctrl T
Ctrl D
etc.

Convert to:

«Ctrl T»
«Ctrl D»
etc.

I tried replacing this (Ctrl\ .) with (Ctrl\ [a-zA-Z]), but the result is Ctrl [a-zA-Z].

CodePudding user response：

Find what:

(Ctrl\ [a-zA-Z])

Replace with:

«\1»

Make sure Search mode 'Regular expression' is selected.
