I have been using tmux for some time now and really like the internal copy buffer. I frequently find myself wanting to copy a command between panes but haven't really found an easy way of doing this.
What I would like is some equivalent of Ctrl+K that moves the data into the tmux buffer. Is there any way of doing this with one key binding? As it is, I could probably get it to work with two (first do Ctrl+K, then a keybinding that via xclip moves clipboard into tmux buffer), but I really would like to be able to do it quickly with just one hotkey.
EDIT: I am running bash as shell in tmux, with evilvte as terminal in Kubuntu 12.04.
