I am a SecureCRT user and was about to install PUTTY as the default SecureCRT settings did not send the key-presses required to trigger ALT-CTRL-R. Digging a bit deeper into SecureCRT settings uncovers a "EMACS" compatibility section where you can enable "Use ALT as meta key". That enabled with the default button under "Send escape for meta key" makes the ALT-CTRL options work.

I hope this may help other users in the future as working with HP ACU CLI is challenging on a small console.
