How does one generate italic font in LyX? I just want to select some text and click something in the menu system or type a keyboard shortcut to do this. I have previously found it in the menu system, but it's not in a place that's intuitive for me so I cannot find it quickly.
Select some text. Then, under the menu Edit > Text Style > Customize... (or right-click Text Style > Customize...)
Under Shape, select Italic:
This translates to
\textit from LaTeX's point of view.
Alternatively you can emphasize an item (translated to LaTeX's
\emph) by using Ctrl + E.
There is a convoluted menu system for this, but the shortcut is Ctrl + E. The 'e' stands for emphasis.
