Tiling window manager for Linux

(Default) Shortcuts

• The default modifier key is Win, also called Meta or Cmd. In the following I just call it Win, because that corresponds to the logo/icon this key has on most keyboards.

Shortcut	Function
Win+D	Start launcher (dmenu)
Win+DownArrow	Focus window below
Win+E	Switch container to split layout. If the container is already split, changes from horizontal to vertical split or vice-versa.
Win+Enter	Open terminal emulator
Win+H	The next window should be split horizontally (to the right)
Win+J	Switch between windows
Win+LeftArrow	Focus window to the left
Win+RightArrow	Focus window to the right
Win+Shift+E	Exit i3
Win+Shift+Q	Close current window
Win+Shift+R	Reload i3 (after changing configuration)
Win+UpArrow	Focus window above
Win+V	The next window should be split vertically (below)
Win+S	Switch container to stacked layout
Win+W	Switch container to tabbed layout

FAQ

for_window does not seem to target window by class

Make sure to use the second string displayed for WM_CLASS by xprop.
