Command + F1 did not shows the more... in IntelliJ IDEA
Which way the F-Keys respond is dependant on this pref  

System Prefs > Keyboard > Keyboard > Use all F1, F2 etc. keys as standard function keys.



Unchecked, your F-Keys will change screen brightness, turn the volume up &amp; down etc.
With it checked they become regular F-keys.

Holding  Fn  will temporarily flip this default for that one keypress.
