FakeVim Ex Command doesn't work in Qt Creator 2.7
I used to use "A" to switch between header and source. but it doesn't work in Qt Creator 2.7 now.
other "Ex Command" doens't work too.
Does :w and :q work?
Go to the FakeVim settings, second tab ("Ex Command Mapping") and check whether "SwitchHeeaderSource" has the "^A$" as "Ex Trigger Expression"
And please note that there aren't many Qt Creator developers attending this forum here, whereas the mailing list and the #qt-creator IRC channel on FreeNode are typically watched.
