Question regarding the form of the aspect of the text in the main window

[Harold Mouras]

Dear Lyx Users, 
I remember having worked with a version of LyX in which the bold text did 
appear as bold when typing. In my current version (2.3.1), this is no more the 
case. 
Is that possible to set LyX to put the text in bold and italic in when typing 
it ? 
Thank you very much in advance, 
Regards,
Harold
