Delphi 1.0 - Editor - Epsilon Block Commands

Hello there

Would someone please tell me the set mark/mark block
commands for the Epsilon keymapping in Delphi 1.0?

Or, alternatively, is there any easy way to use an
external editor? (The IDE doesn't seem to provide an
easy way to reload files, or to recognize that a
file has been changed externally...)

Thanks
Matt
