Support Ctrl modifier: Ctrl-ArrowLeft/Right/Backspace

[fadeevab]

Ctrl/Alt modifiers generate different escape sequences on different terminals. Alt may not work on some terminals while Ctrl works more universally. For example, Ctrl+ArrowLeft generates "\e[1;5D" sequence of 6 characters.

@samuela Generally, I found that initial Alt support didn't work as expected on 2 of my terminals. So, I fixed it and added Ctrl modifier, because Alt doesn't work on 1 of my terminals. They also may generate slightly different escape sequences on different terminals.

woo nice LGTM!

i'm wondering now if you and I were both experiencing similar issues, since I was having trouble in some terminals (iTerm), but not others (xterm.js). Hopefully this was the culprit!

I wonder if we should open an issue on https://github.com/console-rs/console with these findings? It seems to me that they should be recognizing these keyboard combos.

@samuela We can create an issue in the console-rs but, from what I see, they are in a "support mode" and these Ctrl/Alt things are quite hard to unify... The issue could be opend there of course...

[samuela]

oh damn, didn't realize they were in "support mode"... what's the recommended replacement?
