Can specific keymapping be binded to a specific file extension in IntelliJ IDEA?

Question

I'm trying to figure out how, if at all possible, to bind specific keymapping to files of certain extension so that when editing those files (of a specific programming language) I can use keymap X while for other languages I could use keymap Y.

If not possible, is it possible to bind specific keymapping to a project?

And if all is lost, is there at least a shortcut to allow a rapid change of keymapping (that is, without having to open the settings menu, change the selection at the drop-down menu and confirm)?

Answer 1

You can't assign a specific keymap to a specific language, other than by writing a plugin. To switch keymaps quickly, use the View | Quick Switch Scheme action (bound to Ctrl-backtick in the default keymap).
