Typing "O" and meaning the letter... not the origin

I am working on some cryptography worksheets. I need to be able to type letters in as the 'key' (say for a substitution cipher). I'm using the spreadsheet as a place to have an easily editable list of letters. Unfortunately every time I type the letter O (in capitals) it assumes I mean the origin point (0,0) - and it does something weird to anything else I've recently typed into the spreadsheet (seems to undo any recent changes). If I type "O" with the quotes it seems to behave better, but it's really hard to remember to do this if I am just trying out a different key, and quickly type a O where I think it should be. I have never defined the origin point in this worksheet, but it seems to be built in that O means the origin... is there any way to stop this behaviour? Is it just me? Any other suggested workarounds?

Thanks in advance,

Ben

It's the same with e and i


Maybe try defining

O="O"

.. and x and z (z is a bug)

Thanks, I'm glad to know it's not just me! Redefining O doesn't work: "Illegal assignment, Fixed objects may not be changed : Point O"

Will continue to look for other workarounds...

Premature update... "Unfixing" O and redefining O as "O" does seem to work. Thanks Michael!

Where can you do this? In the spreadsheet itself?

No, in the Algebra View
