Ctrl+B shortcuts key does not work python 3

[Harry]

Ctrl+B shortcuts key does not work python 3 with robot-framework-selenium library 4.0.0. Mostly CTRL+B used to see the custom code or keyword to explore. It is used to work in previous version 3.3.1 but not in the current version

I use Pycharm IDE, Plugin --IntelliBot @SeleniumLibrary Patched, python and new version of selenium robot framework.

example keyword name: Open Browser. Please bring the cursor on top and press CTRL + B to see code under the keyword.
