Capture the command

[Artist]

May be I am missing an obvrious functionality.
But how do I put the 'command-name' where my cursor is at the
beginning of the 'c' into kill-ring ?

In other words, I like to yank everything that's upto the last
[A-Z,a-z,-,1-9] character.

ie..
I like to capture 'print-buffer' from the following sentence

Hi I have another function called print-buffer    which  is defined on
C-c-p



Thanks,
Artist.
