refer to: http://fox.mit.edu/xsw/cman.htm for a more detailed list, this is only ment as a quick reference.

keyboard functions:

key combo	Description
F1	general client key command list
P	strobe on/off, turn the blinking lights on your ship on off. only applies to some ship types.
i	intercept, a window will popup and you can type the object name to set a intercept course to.  Names are case sensitive, or enter the object number example "tmr (#35)" you would enter #35.
middle click in radar	automatically sets intercept course to object.
u	drop scanner lock.
y	set weapon frequency, if your frequency matches your targets that you are attacking it will by pass the shields (if raised) and hit the hull.  This is not as fantastic as it sounds since if it hits the hull only it dose not drain your targets energy level therefor target will still be able to fire back and maneuver as opposed to hitting the shield will eventual cripple the ship to a stand still and weapon failure.
e	server commands type help for a list. hit e wall <msg> to communicate without the limitations of "
w	weapons on/off toggle.
