问题
I mistakenly hide PhpStorm's main menu using "View > Appearance" unchecked the menu.
I tried many searches on how to show me the main menu again, after long I found a very simple way to do it.
回答1:
Press Double Shift for Search Everywhere.
Now search for any setting or anything you want to change.
For main menu show/hide Press Double Shift > Actions Search for View | Appearance main Menu Then simply enable the setting.
This might also work for Jetbrains, Intellij, Pycharm, Clion, or any JetBrains product.
