Interesting to see what are your favourite shortcuts in PHPStorm/WebStorm?. If you made a custom shortcut then write it as a custom shortcuts with OS as well.
My favourites are; (macOS)
CTRL + ALT + L - Reformat the code (Custom)
CMD + 8 - Toggle Version Control Window (Custom)
CMD + 9 - Toggle Terminal (Custom)
This is for IntelliJ IDEA but I think it has largely the same shortcuts:
Same like you I also have some favorite php short codes that I use during programming or any other work.I get this idea from ninjaessay when I was searching some specific codes of PHP last year.
