While accent grave is difficult with some keyboard layouts it's definetly more consistend so I updated the keymap to use 'ACCENT_GRAVE' instead of 'TAB'.

It might be worth noting that thumbnail size / directory view in most used file browsers (Windows & Linux) are bound to [Ctrl] + {Mouse scroll].
I'm not against view pie menu in that context, but areas that overlap with generally used software i.e. OS' should be consistent if possible, otherwise it might look like reinventing the wheel.

Hm, wasn't aware of these shortcut actually. there we have a consistency problem, on MacOS it's command + 1/2/3/4. in addition the MacOS colum view dosnt exist in Blender unfortunately but 1/2/3 would still have the sam name at least. We clould go the blender way only and everytjing beyond that needs to be done by the individual user, or we implement both OS shortcuts. I personaly would like to be consistend with everything, but having 3 shortcuts for the same thing is also not great. Is there a general "Blender way" for that kind of problems?

It would be good to have OS specific keymaps with File Browser shortcuts integrated with the OS.
But I have no idea how hard it would be to implement and maintain. I'm just a user.

As far as I can tell, adding this pie menu would not interfere with that feature.
Therefore, implementing the scroll behavior is is a separate feature request, and is not a problem for this patch.

Having multiple shortcuts is not a bad thing, so long as the keymap has enough space for all useful hotkeys.
Items in pie menus often have direct hotkeys.
