Maybe: Several kinds of expansion are performed in order: first brace expansion; then tilde expansion, parameter and variable expansion, command substitution and arithmetic expansion (done in a left-to-right fashion); word splitting; pathname expansion and finally quote removal. Then the alinea about the order and the alinea on quote removal could be removed. > shell-expand-line (M-C-e) > Expand the line by performing shell word expansions.

See HISTORY > EXPANSION below for a description of history expansion. That form is clearer indeed.

That is a nice tip. I didn't realize that it was possible to undo. So normally I would avoid using expansions. :) -- Regards, Mike Jonkmans
