Hello,

is it possible to define something like "aliases" (apologies for the lack
of a better term) for command completion?

If the completed command consists of multiple words, I would like to be
able to type the first letters of individual words and have this
abbreviation expanded to the whole command name (taking into account that
the abbreviation is not a prefix of the completed text).

For example:

ome<Tab> => outcomingmessageeditor
cs<Tab> => changestatus

Best regards,
Peter Slížik
