Kirk,
This is in the XP version, 4.5.2 Beta 4 (but not sure it's also in previous versions as I didn't try it before).
If I set the option to rename during ingest and want to rename the original file obmiting the first character, I have to enter {fbas:1}.
But if I try to enter the ':' in the rename box with 'SHIFT'+';' (to get the ':'), it instead enters a dash '-'. I have to open the caracter map and copy/past the ':' to get it into the rename box.
In all other dialoges with rename options it seems to work fine using 'SHIFT'+';'
