Question for Dayvid, is this where you intend to type a long succession of /me emotes, and so it's repetitively tedious?

If so, you can try this alias. I use something similar for successive /notices and /onotices, that I'll include for extra examples.

Code
/alias /em { me $$1- | editbox -ap /em }

/alias /no { notice $1 $$2- | editbox -ap /no $1 } 
/alias /on { notice @ $+ $$chan [@] $$1- | editbox -ap /on }

After you've added the first alias, you can type the command /em followed by your normal descriptive '/me' text. After hitting Enter, the /em will appear again waiting for you to type more emotes. If you hit Enter without typing an emote, it will just go away and clear the editbox. (Scripting explained: This magical behavior is due to the extra dollar-sign '$' calling $1-, '$$1-' which causes the alias to abort if no text was typed, thus preventing the /editbox command from populating the editbox again.)

Well. At least I won lunch.
Good philosophy, see good in bad, I like!
