[slime-devel] rewriting commands

I am trying to find out how to do this right. Suppose I write a command on the repl and press enter: CL-USER> (1+ 2) 3 then I go back and edit that line, trying to reuse part of what I wrote (in this case, I type "(describe " before and ")" after the previous expression, then press ENTER, ENTER: CL-USER> (describe (1+ 2)) 3 CL-USER> (1+ 2)) and I end up with an incomplete expression (as above) and an error. How can I reuse edited lines from the REPL? Copy & paste with C-K C-Y works, but there must be a better way. Tamas
