Is there a way to discard/kill-line?

[mtrajano]

This might be a really basic question but I have the habit of using ctrl-u to kill/discard the current line, which is the default behavior in fzf. It looks like this key is overriden by the scroll keybindings. Correct me if I'm wrong but it looks like there's no way to do this in tmux-sessionx at the moment and you're instead forced to delete a character at a time. Would you be open to a pr adding the ability to bind this key? This would be the unix-line-discard event in fzf.
