Is your feature request related to a problem?

When NumLock is on, PathOfBuilding treats input from the numeric key pad as expected.

When NumLock is off, PathOfBuilding currently seems to ignore input from the numeric key pad.

Many/most programs on Windows (e.g. Notepad, the dialog in Chrome that I am typing this in, and Path of Exile itself) by default treat keypad input when NumLock is off as follows:

• Keypad "7" = Home
• Keypad "8" = Up
• Keypad "9" = PgUp
• Keypad "4" = Left
• Keypad "6" = Right
• Keypad "1" = End
• Keypad "2" = Down
• Keypad "3" = PgDn
• Keypad "0" = Ins
• Keypad "." = Del

Describe the solution you'd like

When I am typing in PathOfBuilding and NumLock is off, I would like the keypad keys to perform navigation like in other programs on Windows.

Additional context

No response

No files or tests are named. Reproduce the issue in Path of Building on Windows with NumLock off, then trace the keyboard input handling for numeric pad events. Done means the keypad navigation keys perform the listed Home, arrow, Page, Insert, and Delete actions while NumLock is off.
