keyboard shortcuts do not work in web terminal

[matifali]

I do not have a Mac, but on a Windows machine, it does not work on Brave and Edge.
Please take a look at the screen recording. The ^V and ^M characters appear when I press Ctrl+V and Ctrl+V+Enter

I see the same behavior on Brave and Edge.

I found this:

Then middle-click to paste the text. If you want to use the traditional cut/copy/paste commands, you can't use ctrl-X, ctrl-C, ctrl-V with xterm because those either generate interrupts or are passed through to applications. So you have to have to use ctrl-shift-X/C/V instead when cutting or pasting in the xterm.

Looks like there are other ways to implement that but kinda hacky xtermjs/xterm.js#2478. Unfortunately, I can't test them because I don't have a Windows machine.

@BrunoQuaresma Do you think that you can leave here a note justifying whether we can fix it now or we'd rather postpone it for later?

[BrunoQuaresma]

It is a common issue when using Windows or Linux distros and connecting to remote SSH servers since ctrl + C and ctrl + V are terminal/system controls already. We would have to think of a creative solution to workaround this so I would expect more users reporting this issue before a commitment.

@BrunoQuaresma What if we adopt a similar solution to gotty.

It does not seem to be an issue with OS, but rather browsers. Maybe we could enable it for Firefox (clipboard manager)? In other cases, copy-paste could be achieved with mouse selection. Thoughts @matifali ?

EDIT:

This is also an interesting note about gotty:

Now the terminal library is default to xterm, which should support copy&paste on Firefox.
Please reopen if the issue still exist.
