Changing accent behaviour to match iOS In iOS an accent can be added after the character where it is intended. In OSX it is the opposite, it must be entered before. This means that if I forget to add it, I must delete the character, add the accent and then retype the character.

This makes fixing errors in OSX cumbersome and slow. Is there any way to change the behaviour of OSX to match that of iOS?

Many thanks.

EDIT: It is Greek I am trying to type so I've included Greek as the Input Source. I am also using Snow Leopard, in case this makes a difference...
One way is to make a custom keyboard layout using

Another option might be to use system preferences/language &amp; text/text/symbol and text substitution to set up substitutions for the input of the base character plus ' generating the accented character.  But I no longer have 10.6 and can't remember if this feature is present there.
