Expose Scintilla's word part left/right hotkeys

[gene-pavlovsky]

Scintilla provides the following useful hotkeys by default:
Ctrl+\ - move to next word part
Ctrl+/ - move to prev word part
Adding Shift+ to those changes "move" to "select".

In Notepad2, three of them work, except the Ctrl+/ - which is assigned to "Reset zoom". It would be nice to somehow be able to access those hotkeys.

Personally, I don't find Ctrl+,/ very nice and (in another Scintilla-based IDE) I remap them using AutoHotKey, my preferred hotkeys is Ctrl+Alt+Left,Right for moving and add Shift+ to select.
So perhaps those could be mapped to the corresponding Scintilla features?
