Feature request: repeat the last key combination pointing at something

The classic text editor Vim has a . register, which allows to repeat the last action. This could be a useful feature for Vimium C, as well.

For instance, imagine you are trying to side-scroll through a picture gallery, that has static arrow buttons, but doesn't allow to navigate with arrow keys. You have to press f and whatever combination of two keys is then displayed on the software buttons. As the position of those never changes and the number of links on the site stays the same, the combination necessary to push the button also stays the same. This feels clumsy and unnecessary. It would be nice to just repeat the last key combination with . to then easily browse through in such a case.

For consistency, it could be a good idea to instead of literally executing the last combination of keys again, saving the element which was last interacted with and triggering a second interaction from whatever identifies this element on the html-script. Maybe a web-developer can clarify this in a more professional language.

Start by tracing how Vimium handles the f command and key combinations, since the issue names no files, tests, or entry points. Compare repeating the last combination with re-identifying the last interacted HTML element, and define tests that show whether pressing . triggers the intended interaction.
