I use the shift keys a lot and it is an unnecessary strain on the pinky. The `enter` and `backspace` functionalities are conveniently located under a dominant finger (ctrl-m and ctrl-h). Similarly:

But in the vim spirit I want to get this functionality with a key combination rather than finger acrobatics; e.g., lets use the extremely rare key combination `fd`. 

For the alphanumerical keys one could dump an entire list of imaps: `fd1 !`, `fd2 @`, ..., `fda A` etc. into vimrc. I'm hoping there is a better way.

Many thanks!
