i3 is an ultra lightweight tiling window manager with excellent documentation. It follows the Arch Way in that it is configurable through a simple text based config file and is generally badass (well tested, simple to use, small codebase, etc). It is also fast and consumes almost no memory.
i3’s entire purpose is to be controlled through key commands. When you first install it, it gives you a well documented configuration file for you to edit. There are only a few changes we have to make to make i3 vim compatible.
One of the key benefits of using Arch and i3 is that there are no “random” keybindings – everything is documented in your i3 config. This makes it much easier to do things like define Alt+C/V to be copy/paste (for example) – we will get to that when we discuss urxvt
# Mod=Alt -- I use alt so it doesn't conflict with vim or tmux but is easy to reach set $mod Mod1 # kill focused window (vim delete, follows vimperator settings more than vim) bindsym $mod+d kill # dmenu is how you start programs -- make it the same as vim command mode bindsym $mod+semicolon exec dmenu_run # i3 uses jkl; instead of hjkl -- fix that bindsym $mod+h focus left bindsym $mod+j focus down bindsym $mod+k focus up bindsym $mod+l focus right # move focused window bindsym $mod+Shift+h move left bindsym $mod+Shift+j move down bindsym $mod+Shift+k move up bindsym $mod+Shift+l move right # These are more like the tmux config we will get to later, but are intuitive bindsym $mod+backslash split horizontal bindsym $mod+bar split horizontal bindsym $mod+apostrophe split vertical bindsym $mod+quotedbl split vertical bindsym $mod+minus split vertical
