How can I cancel display the menu underline in rstudio?

I know some people like to use the keyboard to operate the menu, but how can I make the menu more concise.

RStudio
Version 1.4.1717

It isn't possible to change this, sorry! If you find the menus unpleasant, you can also invoke commands using the Command Palette: RStudio v1.4 Preview: Command Palette | RStudio Blog
