Lets see... what I use regularly;
On the keyboard;
Up, down, left, right, roll left, roll right, brake, countermeasure, afterburner, messaging (11 buttons at least) (no, voice comms is NOT quick enough for intense FS missions, though admittedly, intense FS missions where you need to micro AI a lot are more or less restricted to multi and a few of the better fredded mods), subsystem target, target turret, target unscanned, target new target, target subsystem in reticle, target targets target, target target attacking target, target ship on escort list, set escort target, target in reticle, target bomb/bomber, target friendly, target hostile, max top speed, all stop, equalise shields, shield management for each quadrant (4 buttons) (if you don't do it you're ****), energy management (7 buttons) (if you don't do it you're ****

), special energy management (default =scroll lock / shift scroll-lock), jump engines, change primary weapon bank, change secondary weapon bank, dual fire missile mode, hot keys(F5-12) (I must get back into the habit of using these more).
So uhh, yea. That's...... 60?
And I'm not using some that other people use all the time.
Including setting auto-targeting, match speed, and auto-match speed, different throttle settings too. Radar range (occasionally useful).
So uhm.
Yea............ No.
