I had a quick look at one of the images on asimov.
(A 1998 lode_runner.dsk.gz containing "Load Runner".)

The keys look to have been hacked (details below) so you could either
check other versions and hope the key handling is in the same place so
you can decode it, or press Ctrl-X, Ctrl-Y and turn around the
joystick. ;-)

$6A34 uses a table at $6B59
9E Ctrl-^ : next level
80 Ctrl-@ : men += 1
9B Esc    : pause game
92 Ctrl-R : abort game
81 Ctrl-A : abort level
93 Ctrl-S : toggle sound
8A Ctrl-K : keyboard mode
8B Ctrl-J : joystick mode
88 Ctrl-H : slow down game
95 Ctrl-U : speed up game
98 Ctrl-X : switch X axis
99 Ctrl-Y : switch Y axis
8d Ctrl-M : high scores

Cheers,
Nick.
