Depends what you want.

if you are looking for testing, then there is no real needs.

if you are making a manual handwheel, then all of the above.

if you are just jogging the machine, then a manual selection switch
for the axis is approprate.

ditto for speeds max feedrate is that of the machine. a seperate
button for rapids would be desired.

and yes on accel and decel.
