Modifier keys in text input

[arthurk]

I was wondering if it would be possible allow modifier keys (Ctrl, Alt, Cmd, ...) to be entered into the text input and have them analyzed. For example:

vim foo.txt
iI'm writing some text here<esc>:w
:wq
cat<ctrl+c>
bat f<tab>

Beside characters we could also see which modifier keys are being used the most.
