When in the options menu, clicking on one of the options button will take you inside that category's key binds and options.

When on the general options screen, the game will display the text in the button ending with three dots (Ex. "Controls...") and without them ("Controls") when inside the category itself. However, this is not the case for every category.

-Controls... -> Controls
-Skin Customization... -> Skin Customization
-Video Settings... -> Video Settings
-Language... -> Language
-Accessibility Settings... -> Accessibility Settings...
-Chat Settings... -> Chat Settings

Dot-less variants for each of these exist inside the Crowdin project.
