Rather than navigating menus you can add the most used items into the BB Quick Menu.
If you are running Biab As Administrator:
To run script only .ahk install https://www.autohotkey.com/ and set AutoHotKey.exe to Run As Administrator

Let me know what actions you need and I will give you the function code.
You have the text name up the top that runs the associated function below.
You can change the font size and color as well as the background color.
The script can be compiled to an exe when you have all the functions you need.

Copy the code and paste into Notepad then save as BB Quick Menu.ahk
