I have a trivial macro that automatically pares levels of replies.
Choose how many >>>>...>'s you want to be rid of (use ctrl-F, then cancel), then let 'er rip.
Works in Agent composition window, running in Macro Express, but probably easily adaptable to other tools.
Here 'tis (I call it with ctrl-alt-F)...
REPEAT F3 shift-End Delete Delete RepeatEnd
In Macro Express this is terminated when a "Find" window pops up... your set of >>>'s no longer found... all those lines cleared. ...Jim Thompson
