I have just started using the Vimium plugin for Chrome and I am kicking myself for not using it earlier. It is packed with features that make web browsing much easier, and also uses very similar shortcuts to the popular terminal editor Vim (hence the name). One of my favorite features of Vimium is the ability to select a link by pressing f followed by the letters associated to a link. This plugin (along with the link select feature) as gotten me to rely on the mouse much less when doing computer work (which is the goal).
So, I was wondering if there exists a window manager that has a feature similar to the link select feature of Vimium. The majority of my mouse use is for changing focus of windows (which is a waste of time). I understand that there is the Alt-Tab and Alt-Esc shortcuts that can be used to change focus, but that requires me to move through a list and its not always clear which window belongs to which program.
So my question is, what window managers exist that implement a window selection feature similar to the link selection feature of Vimium?
