The easiest way I found to do this is to convert the hotkey to a context
menu command event.  Context menu events typically use the right click
mouse position to begin an operation.  A hotkey is a shortcut for
context menu actions.  Most, if not all of the context menu entries that
have equivalent hotkeys are already defined.

See my comments above.  Over time, I have slowly converted the hotkeys
over to context menu command events where applicable to reduce duplicate
code.  As to whether or not this makes sense somewhat depends on how
long before the schematic editor is converted over to use GAL and the
new tool framework which handles hotkeys differently.

I cannot comment on this since I'm not a mac user but there are some
rather interesting bits of code that attempt to normalize key modifiers
between platforms in both wxWidgets and KiCad which could cause issues.
I would like to avoid ugly #ifdef OSX/#endif code as much as possible.
