Supporting multiple modifier key recognition (like Ctrl+Shift)

[curlpipe]

Is your feature request related to a problem? Please describe. This is a great library, probably one of the most complete libraries I have found. The problem I'm finding is that the users of my program (that uses Crossterm) wish to be able to use keyboard shortcuts such as Ctrl+Shift and Alt+Shift etc... When I try implementing these modifiers, it just registers as usual Ctrl and Alt keys.

Describe the solution you'd like I'd like to be able to bind multiple modifier keys on top of each other. E.g. Ctrl + Shift + S or Ctrl + Alt + R etc...

Describe alternatives you've considered in any Not really sure how to get around this, I could maybe write some janky code to work around this using another library or using libc for now but I don't want to go into that territory.

Additional Info This can kinda fit into issue #510 as I think it's mentioned there But I wanted to make it clearer

Many thanks :)

Example key codes sent by gnome-terminal:

Up: \e[A Shift Up: \e[1;2A Alt Up: \e[1;3A Shift+Alt Up: \e[1;4A Control Up: \e[1;5A Control+Shift Left: \e[1;6D

Can this be closed with the addition of the keyboard enhancement feature to 0.25?

Is this implemented? In my app I tried to catch Ctrl + Shift + c (Ctrl + C) but couldn't. FYI, changing the key from c to e.g. 'z' does not work either. If I miss something, please let me know.

This can be done using the KeyboardEnhancementFlags if you have a terminal that supports it.

As of two weeks, it is supported by Alacritty: https://github.com/alacritty/alacritty/commit/cb03806e2ab85674c45e87e1bb24dfe2fd1a918c
