Keyboard shortcut for Repeat Search does not work

According to the Pinegrow Help (Support | Keyboard shortcuts), you can search in the code editor using keyboard shortcuts: CMD-F for Search, CMD-G for Find next.
But in fact CMD-G opens a “CSS Grid” popup window.
Is there any way to configure this behaviour?
I’m working on Windows 7 64bit with Pinegrow 5.41 PRO Personal.
