Saving output to somewhere easily accessible?

I am using mushclient and my mud lacks a 'last' or 'history' command so i thought it would be nice if I could make a trigger or something to take output from channels/says/etc and save them. i was thinking a separate trigger/place to save/command to retrieve the saved info for each channel/etc.

So for example I moght get:
Joe says to you Hey whats up?
Trigger catches that and saves it somewhere
Then i have an alias or something called 'lastsay' so that when I type 'lastsay' it displays all my previous data that has been stored(possibly) with a 10-50 line limit?

is this doable? It seems like a complex thing to me.

MUSHclient lets you set up large output buffers (eg. 500000 lines) so you can keep quite a bit of scrollback.

You could also set up a trigger and for each matching line append to a notepad window, effectively making a copy in a separate window.

You can also set up logging in MUSHclient, so you could simply log everything.
