fakevim is based on eventFilters installed on a QTextEdit or a QPlainTextEdit.
It basically catches all keystrokes and modifies some internal state that
make the resulting text in the editor look like it was using vim.
There are only a few files in here:
fakevimplugin.{h,cpp} - interaction with the rest of Creator
fakevimactions.{h,cpp} - settings
fakevimhandler.{h,cpp} - the "real" event
There are some more hints for developers in fakevimhandler.cpp
