This command puts text into the input buffer. It is not really useful from the normal command line, but is quite useful when called from a macro to redefine macros, or perhaps when bound to a key to speed up part of a line (macros allow you to largely do what this would allow, however). Any text already in the input buffer is discarded.
/def reedit = /grab /edit %1 = $%1If you had previously done "
/def flail = :flails at his keyboard", the command "
/reedit flail" would place "
/edit flail = :flails at his keyboard" in the input buffer and allow you to edit it using the editing keys. See "evaluation" for details on how macros like this work.
