New member, simple question

Another way would be to use the “Define” key (Shift Xtθn) this way:
Name: Inmm
Function: CONVERT(X*1_(in),1_(mm))
(Let X checked)

You can call it the same way than above (user defined key), or using the Catalog (Suitcase) key.

I don’t really like user defined functions with the “Define” key for my everyday tools, because deleting them is so easy that I reserve the use of this key for transient functions. Using programmed functions is more persistent.
