Is it possible to minimize all functions at Android Studio at once?

Question

When working on a class with thousands of lines, minimizing some functions on the IDE makes it very handy to manage the code.

However, everytime we restart the IDE; or close the function: it will be re-opened again.

Is there a way to keep your 'minimizing' preferences?

Answer 1

(for windows Users)

Same time All Methods Collapse : CTRL + SHFT + -

Same time All Methods Expand :CTRL + SHFT + +

(for Mac Users)

Same time All Methods Collapse : Command + SHFT + -

Same time All Methods Expand :Command + SHFT + +

Answer 2

You can go to Code > Folding > Collapse All

In my case the short-cut is CTRL+SHFT+/.
