i actually have this problem also with my azerty keyboard and when selecting french (which uses azerty) in the switch locale settings. If i press the W key in the editor it actually types correctly the W character as it should, However the W key sits at the place where Z would be on the qwerty keyboard (W & Z are switch physically on the keyboard). But i intially tought there was no keyboard shortcut for undo as i tried ctrl-z while i later found it ctrl-w worked so it has to do with azerty keyboard (and maybe scancodes) and perhaps keyboard locale settings on the nintendo switch. Now that it know it it's not that big of a problem would have been more of a problem when the editor actually typed Z instead of W :)
