window maximize on Linux

Would you like to maximize window on Linux ?

I found how to solve this problem.

Alt - Space x

Alt and Space key simultaneously then displays menu from top of window then strike x.

You can use the maximized window(web browser, xterm ....)

Reverse method is same the maximize.

Happy linuxing :)
