While working in the table environment in ArcMap, I am not able to write several Polish characters without causing some action. Trying to write ą (AltGr+a) results in a Select All, ń (AltGr+n) ends up with flashing the select object, Ż (Shift+AltGr+Z) results with undoing last action, while writing Ś (Shift+AltGr+S) ends up with displaying Advance Table Sorting window. How do I turn off those shortcuts? I can't really find them in Customize Mode.
