I've not noticed this feature  - I must give it  a go.

But most version (SunOS 4.1 etc) use a time out so that if 
an ESC and another char is received in quick succession
it is treated an ESC sequence, otherwise it is an ESC and then the
char.  This make curor movement in insert  mode a macroable thing.

This seems to be how all multiple char marcos are handled.
