You can use m-p/n as you mention, same as, say, in regular bash, or search. Or c-c c-p, c-c c-o etc.

But TBH I mostly just use the ordinary ! syntax (e.g. `!!` or `!bla:*` or !200 etc) because it’s even faster and works fine even when no editing is available at all.

So if I used find to search for an executable it’s just so effortless to type ./`!!|head -1` rather than searching up, selecting and copying a region, going back to the end, editing it, blah blah. Or even worse, reaching for the mouse.
