Hi, we have a bug report that keybindings with Alt does not work in gvim if the X input method is enabled:
Testcase :set wak=no # disable keybindings for the menu :tabnew :map <M-1> 1gt :map <M-2> 2gt This should allow you to switch with Alt-1 and Alt-2 between tabs, but this does not work. The workaround is to disable X input method (with ":set imdisable"). Then it works. Maybe there's some relation to http://bugzilla.gnome.org/show_bug.cgi?id=331369. In the code it seems that GtkEventKey->state field has set Meta1 correctly. So the code in (vim) gui_gtk_x11.c:key_press_event() seems to be the cause. Regards, Matthias
