I installed Arch Linux a few days ago on my Chromebook C720, but due to some kernel support issues with the touchpad, I'm left with no mouse. I'm not too bothered about fixing it right now though, because I figure it's a good chance to learn how to do things more efficiently - with just the keyboard.
So I've installed i3, Vim, Ranger, Pentadactyl, and a bunch of other keyboard-based programs, and things are going surprisingly well, except for the lack of ability to click on certain JavaScript buttons, such as the vote buttons on this site. Pentadactyl's hint mode doesn't work because they're not hyperlinks.
Am I missing something, or is this just not possible with Pentadactyl?
