It is better to put parenthesis after the name: ckKeyBts()
The perlsub document explains the difference and why this is better:
perldoc perlsub

If you define the sub before you use it then barewords are fine:
sub ckKeyBts {
# do something
}
ckKeyBts; # bareword works ok
Or you could declare the subs at the top of the program and define them
later:
sub ckKeyBts; # declare that this will be defined later
ckKeyBts; # bareword works ok
sub ckKeyBts {
# do something
}
