Terminal: Support broadcast input?

[shuosiw]

Description of the new feature/enhancement

Sometimes i need to open many panes in a tab with splitHorizontal/splitVertical hotkeys. And then broadcast input to all the panes in current tab, or all tabs.

Is it possible to support broadcast input, like iterm2?

I suppose there's no reason we _couldn't_ support this.

It might need some refactoring to have a TermControl raise an event up to the App layer to have it transmit the input to all the terminals in the tab/window, but that's certainly possible.

@zadjii-msft
It is useful to maintain a series of servers with the same role. And now other popular terminals all support this feature, like iterm2 on OS X, cmder/conemu on windows, xshell/securCRT and so on.

SO PLEASE consider adding this feature!

Send the same command to all the active tabs within windows terminal

I hope windows terminal come with a feature that it can send the same command to all the active tabs.
Let's say we open 4 tabs within terminal,then each tab have a connection to a SSH server. and we want to know the status of the firewall on those server by issue "systemctl status firewalld" . but we want do it in one time. not one by one for each connection in these 4 tabs.

This feature had been implement in SecureCRT.

Bellow is the steps to send the same command to all active tabs in SecureCRT.

This can be done using the 'Chat Window'.

1. Select 'Chat Window' from the 'View' menu so that the window will be displayed.

2. Then just right click inside the 'Chat Window' and select the 'Send Chat to All Tabs' option in the pop-up menu.

3. Once enabled, any commands entered in the 'Chat Window' will be sent to all tabs when 'Enter' is pressed.

It will be very handy in daily task if it can be like that.

We sure need that~

I am also very interested in this feature, and want to emphasize the multiple modes of broadcast operation that iTerm2 supports. It's important that broadcasting to all panes _in the current tab_ be supported distinctly from broadcasting to all panes in the window.

This is the only missing feature keeping this terminal from being used ubiquitously in my organization. Please add support for this!

Just throwing my six cents in on this, very interested as I've come from iTerm2 and also would find it very useful if there were options to broadcast to all panes in the current tab, as well as all panes in all tabs.
