Thanks. I can reproduce everything you say, in all Emacs versions I tried, trunk is among them. And indeed it contradicts the manual, which says that "You can put more than one mouse button in a key sequence". Can you please make a bug report (M-x report-emacs-bug)? Please give a minimal example starting from emacs -Q, and please include the information that this also happens in trunk. BTW, I tried hard to find a workaround to make possible what you want, but failed. Reading key sequences generally seems to terminate after any mouse event (try `read-key-sequence'!). The only thing you can do is to bind mouse-8 to a command (a keymap does not work) that reads another event and DTRT. Regards, Michael. > 1. Yes, it happens with emacs -Q. > > 2.
