📄 Description

Summary of the Pull Request

Alt-Numpad# input would be escaping each numkey before sending it through. This would result in some weird behavior, for example, in powershell, where the first alt-numpad# would start digit argument and once the user releases alt, a character is sent through and digit argument would repeat that character X times. To resolve this, we simply need to ignore KeyDowns where Alt is held and a Numpad# is pressed.

Once Alt is released, we'll receive a character through TSFInputControl, not TermControl::CharacterHandler. It seems that the CoreTextEditContext in TSFInputControl intercepts the character before it gets to TermControl. TSF will then send the received character through as normal.

PR Checklist

Validation Steps Performed

Testing various combinations of Alt-Numpad# consistently sends through only one instance of the expected symbols.
