Text Editor : Add shortcut for dialogs

[Tilix4]

I'm thinking about a shortcut to improve dialog writing. Using this shortcut, it would automatically write the previous character. We could use Ctrl + e / cmd + e (osx), because this shortcut is not used by atom by default.
Like :

STEEL
Beer's ready!

BRICK
Are they cold?

CTRL + E

STEEL (Automatically written)

Pressing this shortcut several times would iterate in a list of characters present in the current scene. In that way, this shortcut could be used even for dialogs with more than two people.

That's a cool idea. Maybe could even be applied more generally. Like hotkeys for looping through common structural values.

That also makes me think... Could we do something similar to an autocomplete?
