windows, or toolbar windows (GIMP or similar). Those windows usually set the
appropriate hint and are opened in floating mode by default.
-You can enable floating mode for a window by pressing +mod+Shift+Space+. By
+You can toggle floating mode for a window by pressing +mod+Shift+Space+. By
dragging the window’s titlebar with your mouse you can move the window
around. By grabbing the borders and moving them you can resize the window. You
can also do that by using the <<floating_modifier>>.
*Syntax*:
---------------------------------------------
-new_window <normal|1pixel|borderless>
+new_window <normal|1pixel|none>
---------------------------------------------
*Example*:
for_window [title="x200: ~/work"] floating enable
------------------------------------------------
+The valid criteria are the same as those for commands, see <<command_criteria>>.
+
=== Variables
As you learned in the section about keyboard bindings, you will have
== List of commands
+Commands are what you bind to specific keypresses. You can also issue commands
+at runtime without pressing a key by using the IPC interface. An easy way to
+do this is to use the +i3-msg+ utility:
+
+*Example*:
+--------------------------
+# execute this on your shell to make the current container borderless
+i3-msg border none
+--------------------------
+
+Commands can be chained by using +;+ (a semicolon). So, to move a window to a
+specific workspace and immediately switch to that workspace, you can configure
+the following keybinding:
+
+*Example*:
+-------------------------------------------
+bindsym mod+x move workspace 3; workspace 3
+-------------------------------------------
+
+[[command_criteria]]
+
+Furthermore, you can change the scope of a command, that is, which containers
+should be affected by that command, by using various criteria. These are
+prefixed in square brackets to every command. If you want to kill all windows
+which have the class Firefox, use:
+
+*Example*:
+------------------------------------
+bindsym mod+x [class="Firefox"] kill
+------------------------------------
+
+The criteria which are currently implemented are:
+
+class::
+ Compares the window class (the second part of WM_CLASS)
+instance::
+ Compares the window instance (the first part of WM_CLASS)
+id::
+ Compares the X11 window ID, which you can get via +xwininfo+ for example.
+title::
+ Compares the X11 window title (_NET_WM_NAME or WM_NAME as fallback).
+mark::
+ Compares the mark set for this container, see <<vim_like_marks>>.
+con_id::
+ Compares the i3-internal container ID, which you can get via the IPC
+ interface. Handy for scripting.
+
+Note that currently all criteria are compared case-insensitive and do not
+support regular expressions. This is planned to change in the future.
+
=== Splitting containers
The split command makes the current window a split container. Split containers
workspace 1, 3, 4 and 9 and you want to cycle through them with a single key
combination.
+To move a container to another xrandr output such as +LVDS1+ or +VGA1+, you can
+use the +move output+ command followed by the name of the target output. You
+may also use +left+, +right+, +up+, +down+ instead of the xrandr output name to
+move to the the next output in the specified direction.
+
*Examples*:
-------------------------
bindsym mod+1 workspace 1
=== Resizing containers/windows
If you want to resize containers/windows using your keyboard, you can use the
-+resize+ command, I recommend using it inside a so called +mode+:
++resize+ command:
+
+*Syntax*:
+---------------------------------------------------------
+resize <grow|shrink> <direction> [<px> px] [or <ppt> ppt]
+---------------------------------------------------------
+
+Direction can be one of +up+, +down+, +left+ or +right+. The optional pixel
+argument specifies by how many pixels a *floating container* should be grown or
+shrinked (the default is 10 pixels). The ppt argument means percentage points
+and specifies by how many percentage points a *tiling container* should be
+grown or shrinked (the default is 10 percentage points).
+
+I recommend using the resize command inside a so called +mode+:
.Example: Configuration file, defining a mode for resizing
----------------------------------------------------------------------
bindsym semicolon resize grow right
bindsym Shift+semicolon resize shrink right
- bindcode 36 mode default
+ # back to normal: Enter or Escape
+ bindsym Return mode "default"
+ bindsym Escape mode "default"
}
# Enter resize mode
