It's pretty much done, except for one last question. I want the bubbles to show the command name, the prefix arg, and the key sequence that was used to call the command. All that works fine, except if the command was called via M-x, ie `execute-extended-command'. In that case, `this-command-keys' returns "RET", which isn't quite right -- I'd rather it showed "M-x" or whatever. This is the basics of how it works (this is put into the post-command-hook): (let* ((command-name (symbol-name this-command)) (pref-arg current-prefix-arg) (keys (this-command-keys)) (key-string (key-description keys)) (title-string (if pref-arg (format "%s %s" pref-arg key-string) (format "%s" key-string)))) (alert command-name :title title-string)) I don't want to just check for "RET" and replace it with "M-x", because the command might very well have been called with "RET". Do I have any other way of knowing for sure that the command was called using `execute-extended-command'? last-command doesn't seem to get it either... Thanks, Eric
