var key HP50

[tgahan]

Hi Everyone
Question: How can I get the back to the original menu boxes: EDIT VIEW STACK RCL PURGE CLEAR
I accidentally pressed the VAR key in RPN mode.
My menu boxes at the bottom of the screen changed to PPAR ODETY CASDI

I tried pressing VAR key again but did not work and also ON (CANCEL) key
The only way I could get back to the original menu was a warm reboot (ON + F3)
and this wipes everything from the stack.
There must be another way. I only have the calculator 3 days so I am a novice.
The ROM version is 2.15 which is the latest (I think)
Thanks for your time.
