This should be equivalent:

    for d in $( echo $PATH | sed -e 's/:/ /g' ); do ls $p/k*; done | less

'complete' is the action, not the command.  <tab> completes file
substitution to the next non-arbitrary point.  Repeat <tab> lists
alternatives, as you've found.

'complete-into-braces' (M-{) might give you what you want:

    [karsten@superego:karsten]$ k
    Display all 191 possibilities? (y or n)
    [karsten@superego:karsten]$ k               # hit <shift><alt>{
    [karsten@superego:karsten]$ echo k{eysign-fingerprint,mself@knight.gregfolkert.net,noppix} 
    keysign-fingerprint kmself@knight.gregfolkert.net knoppix

    man bash
