Remember What You Typed

I run another game, and in my game, groups of players are called guilds. The shortcut for talking in guilds is /g. I'm not asking that /g be used for talking in "clan", but I'm asking that when you type something and you get "Command does not exist!", it says "Command does not exist! You said: hi there folks, this is what I typed and accidentally used a /g instead of a /c and I cannot remember all of the nuances that I used that made my sentence just perfect for my clan.". Thank you for your consideration Stabzs.
