Looking into it I found that it is a bit non-trivial to unread a command key sequence. I am not sure I have got every thing correct but this is what I am using now ;; Unread the last command (setq last-command-char nil) ;; For viper (setq unread-command-events (listify-key-sequence (this-command-keys-vector))) The missing bit that lead to the looping was setting last-command-char to nil. Maybe something like this could be included in the manual in (info "(elisp) Event Input Misc")?
