Cannot add extra line to find text box in find widget

[stevencl]

Issue Type: Bug
Testing #79831

Copy a multiline selection from the editor and paste into the find input box of the find widget.

The find widget shows multiple lines as expected.

Try adding a new line with shift+enter - nothing happens
Try adding a new line with ctrl+enter - nothing happens

Shift focus to the replace text box and paste in the same multi line text from the clipboard. The replace text box shows multiple lines as expected.

Try adding a new line with shift+enter - a new line is added

I expected to be able to add a newline in the find text box the same way I was able to do in the replace text box.

I pushed a fix for pressing ctrl+enter when the cursor is at the beginning of the find input box. Previously it doesn't insert a new line but now it does.

Shift+Enter is bind to Go to Previous Result by default, if you wish to use this one in the same way as other textareas, you can now unbind it from the command

	{
		"key": "shift+enter",
		"command": "-editor.action.previousMatchFindAction",
		"when": "editorFocus && findInputFocussed"
	}
