I'd like to find a way for KM to type the first 6 characters of a variable (but not the full variable) into a field. (So if the variable has been assigned the value "ABCDEFGHIJKLMNOPQRSTUVWXYZ," I'd like KM to type "ABCDEF.") In a spreadsheet I might use a LEFT() function to achieve this, but I don't see any likely candidates in the KM functions list.
Am I missing a function? Any other clever ways to get that to happen?
