Terminal window height shortcut not working

I'm using PhpStorm EAP 138.1289 on a mac.

When I use the shortcut Cmd + Shift + Up Arrow to "stretch to top",  instead, it cycles through the command history.
The keymap shows Cmd + Shift + Up Arrow is supposed to increase window height.

While I'm at it, I know that Opt + F12 will cycle between the project window and the terminal window. But, is there a way to cycle between the two without hiding the terminal window?

Thanks,
Rick
