most-recent-file completion and accept-line

[Eric Smith <es@xxxxxxxxxxxx>]

One of the most useful lines in my config file is:
bindkey '^O' most-recent-file

How do I bind a key combination to complete the most recent file
and then automatically run accept-line or <enter> on this
filename?

(my preexec function will do the necessary on the file).

thanks a lot :)
