The menu command works fine. The keyboard shortcut does nothing.
I’ve reproduced this on two machines. One is an ancient Dell server running Win2003. The other is a recent laptop running Win7 64bit (and ST2 64bit), both with the builtin keyboard and a wireless one. About the only thing the two machines have in common is a UK keyboard.
sublime.log_input(True) shows nothing at all for Ctrl-
. It shows plain just fine (0x60), and Shift-
(0xac), and AltGr- (0xa6), and Ctrl-c (control+c). But not Ctrl-`.
I’m pretty sure I’ve hit another ST2 feature which only worked from the menu rather than the advertised keyboard shortcut, but unfortunately can’t remember what it was.
