Scroll with vim-movement keys: h,j,k,l
To scroll pages with h,j,k,l keys (like vim), I’ve installed the firefox extension vimkeybindings.  With it, I can be working in a vim window where I use a lot the h,j,k,l keys, do Ctrl-Tab to switch to firefox window, and scroll around the firefox webpage with the same h,j,k,l keys, without having to displace my fingers to the arrow-keys and back again. I do this a lot, and doing it this way makes it much more fast/uncumbersome 🙂
Also, the default firefox shortcut for the search-bar is Ctrl-j or Ctrl-k, which complements very well with the vim-movement keys 🙂
 If you are a vim power user, there are other more-complex firefox extensions that bring more vim-power into firefox. The vimkeybindings is simple and a good match for what I want for the moment.
1 bar for url + search
To make firefox have only one bar for the url and search (like chromium) , I use omnibar
After a long-time relationship with screen I also got to a point when tmux was more compeling… and there I go, into the tmux world, in a peacefull move (nothing bad said about screen ! there are already too much screen-hate-converted-tmuxers…)
Here I leave some personal notes for the switcher:
/etc/tmux.conf – system-wide
~/.tmux.conf – user-only
If terminal colors are all messed up (in vim and such)
I document my crazy projects with Markdown syntax – it uses only text, but still allows to express a rainbow of effects like *italic* **bold** bullet-lists, hierarquic headings… insert code (multiline or just short-pieces)
The template I use is published as a github repo called strapdown_template and is pretty easy to use.
If its usefull to anyone else, or if you know a better way, don’t be shy and drop a comment 🙂
