[keybind]Maximize after Execute

view story

http://crunchbanglinux.org – Hello.It was unexpectedly to find a lot of keybinding's features in Openbox. I realised all hotkeys what I want except one. I want to execute mc in new maximised window. If I write <keybind key="C-A-m"> <action name="Execute"><command>lxterminal -e mc</command></action> </keybind>mc runs in small window, and I have to maximised it manually( Such actions as "Maximize" applies to current focused window, so I can't write them into this <keybind>.Can anybody help to make this process automatically?
