[Feature Request] Make Ctrl-Enter hotkey submit P4 changelist

In p4v, you can be typing in the changelist description and press Ctrl-Enter to submit the changelist. Pressing enter alone adds a new line.

In the Unreal Editor submit changelist dialog, pressing Enter adds a new line, and pressing Ctrl-Enter adds a new line.

Please add the Ctrl-Enter hotkey to the Perforce submit dialog to make it easier to submit changelists.
