Key mappings break keyboard layout

[teoric]

The Mac key bindings provided by the package interfere with standard use of "Alt" to get special characters. Sublime Text does not allow to remove such bindings, which means that users of your package cannot ‘fix’ the key bindings without forking your package. Therefore I would like to ask: Would it be possible to (a) change them to something like "Alt+Strg+:" or to move them to the documentation as ‘suggestions’? This would be a great service to users that need their special letters ;-).

Also, it seems to me that the use of "Alt" without Super (=Cmd) as a modifier is quite ‘unmaccy’; wouldn't it make sense to replace "Alt" by "Super", anyway? (However, Super+: and Super+; are system-wide spell-checking shortcuts on my setup.)
