is there a shortcut to reduce the code in android studio

Issue

i have big code in every file in my project and i need a shortcut to reduce the whole code in specific file with one click instead of doing it manual

i have taken screenshot to explain it

in my case i am clicking manual to every single line and every time i am restarting android studio it expanded again i don't know why

is there a way to do it

void help(){
print('i need help') ...
}
