Shortcut triggered when entering ASCII/Unicode characters in text edit mode

Summary:

When editing text and entering an ASCII or Unicode character using alt and the number pad, Inkscape shortcuts are triggered.

See microsoft.com

Steps to reproduce:

• open Inkscape
• create an object (any shape) and assign a color (not a shade of black)
• create a text object
• edit text object:
  • add an en-dash – by holding alt and entering 00150 on the number pad (-> colored object will be shown in grayscale)
  • press alt + 5 to toggle grayscale mode back to color (-> a ♣ will be added to the text and object is shown in color)

What happened?

The moment 5 is pressed together with the alt key, the viewing mode toggles to/from grayscale (default shortcut alt + 5).

What should have happened?

Shortcuts, in particular alt + numpad, should potentially be ignored while editing text.
